To: VICIS CAPITAL MASTER FUND




Dear Mr. Stastney:




     As you are aware, since China Hydroelectric Corporation closed on the sale of
$50,000,000 of Secured Exchangeable Notes on November 10, 2007 it has made considerable
progress. This is evidenced, in part, by the execution of (i) a Share Transfer and Capital
Increase Contract with Yunnan Huabang Electric Power Development Co., Ltd. (the “Yunnan
Purchase Contract”), to purchase the equity of Yunnan Huang, the owner of the assets of the
Binlangjiang Hydroelectric Power Station Project I for an aggregate consideration of
approximately $22,600,000, including $6,500,000 for the purchase of the equity and
$16,100,000 for the repayment of outstanding debt (the “Yunnan Transaction”) and (ii) an
Asset Purchase Agreement to purchase the assets of the Dong He I Project, principally
including the Li Yuan Hydroelectric Power Station (the “Li Yuan Purchase Contract”)
for an aggregate consideration of $9,900,000 and a Loan Agreement for $5,000,000 to
pay for a portion of the Dong He II Project, the Fengziyan Hydroelectric Power
Station (the “Li Yuan Transaction”, collectively with the Yunnan Transaction, the
“Business Combination”). Terms used herein but not otherwise defined shall have the
meaning ascribed to them in the Note Purchase Agreement (the “Note Purchase Agreement”),
dated November 10, 2006, by and among China Hydroelectric Corporation, an exempt company under
the laws of the Cayman Islands (the “Company”) and the Purchasers (as defined in the Note
Purchase Agreement).



     We anticipate closing the Business Combination on April 16 at 10:00 am New York time.



     As we have discussed with you, the core documents which are prepared in connection with
these transactions are (i) the purchase agreement, (ii) the legal due diligence report,
(iii) the asset appraisal report, (iv) the engineering report and (v) the independent
accountants report. We have attached those same documents which are related to the
Business Combination as exhibits hereto. An index of those exhibits is attached hereto as
Exhibit A. As discussed, we will send you a pro forma capital structure for the Company
prior to the closing.



     We are writing to request that you .(i) approve the Company closing the
Business Combination, (ii) approve the exchange of the $41,000,000 in Notes held by
Vicis Master Capital Fund for 6,833,333 shares of common stock and 18,666,666
warrants to buy common stock of the Company, and (iii) approve the release, prior to
April 16, from the Cash Collateral Account of the $41,000,000 invested by Vicis Master
Capital Fund. Upon the release of these funds, the Company will pay the Holders a
business combination payment equal to 5% of the principal amount of the Notes purchased.
The payment to Vicis will be $2,050,000 plus any interest due at this time. Morgan
Joseph will also be paid a fee of $2,460,000 (6% of the Notes exchanged into equity
securities) which is due at the time of such exchange.



     Please be advised that if you approve those actions set forth in clauses (i), (ii)
and (iii) then the Company will proceed to closure of the Business Combination as soon as
possible. With



 









 







your approval, and the expected approval of the other Holder, the Company will have sufficient
cash resources to pay the consideration required to close the Business Combination. No
Holder is expected to vote against the closing of the Business Combination.



     By executing below, you hereby (i) approve the Company closing the Business Combination,
(ii) approve the exchange of the $41,000,000 in Notes held by Vicis Master Capital Fund for
6,833,333 shares of common stock of the Company and 18,666,666 warrants to buy common stock

1.3.1 Description of the river basin and hydropower cascades planning




     The Binglang River is the up-stream section of Dayin River, the 1st step tributary
of Yilowadi River and is originated from Guyongjan Mountain in Tengchong County. In the river
basin, there are rich precipitation, good plantation and plentiful underground water with stable
water production. The Binglang River as one of medium size river with comparative rich water
resources has a total length of 120.2 km, river basin area upward of river estuary of 2310.69
sq.km, mean annual flow of 128 cu.m/sec and natural drop of 1,200 m.



     In the Binglang River’s main stream plan, there are 2 reservoirs and 9 cascades hydropower
stations with a total installed capacity of 666.9 Mw. The total volume of each of the two
reservoirs is 206 million cu. m and 226 million cu.m respectively. The project Binglang River
Hydropower Station is the No. 8 cascade. All the 9 cascades stations have been completed or are
under construction except the 1st cascade Sanchahe reservoir station which is still to
be constructed.



1.3.2 Status quo of B.H.S.




     As stated in the introduction, B.H.S. is a diversion type station, located in Xingba Village
of Yingjiang County. Its construction was started in April, 1985 and was completed in June, 1988.
The original installed capacity was 3 x 6,300 kW and was raised to 3 x 7,000 kW with an average
annual generation volume of 13.815 million kWh and an annual utilization hour of 5,904 after
technical renovation in 2005 and 2006.



     The B.H.S. is a run-off diversion type station and composes of head-structure, diversion open
channel, head tank, penstock, powerhouse and step-up sub-station, etc. The dam is of concrete
enclosed masonry overflow gravity type with sluice gate and intake gate on the left side of the
river bed. The diversion channel is placed alongside the left bank of Binglang River from Xiaka
village to Qinba with a total length of 2,049 m. The head tank, located on the hill rear of power
house is of narrow strip type; the single supply form is used for the intake chamber with the
penstock closely connected to the fore bay and perpendicular to the powerhouse. The length of each
penstock is 83 m. The power house is located on the 1st step land in the left bank of
Binglang River. The main power house is divided into the main units section and the erection bay. 3
units of Francis type turbine generators are installed in the main units section. The auxiliary
room is located in parallel with and on the up-stream side of the main power house. The step-up
sub-station is located on the hill side left to the auxiliary room. The access road enters the
station area from down stream river bank.



     The 3 Francis turbines installed in the B.H.S. is of HLTF38-LJ-160 type with a runner diameter
of 1.6 m, rated head of 38.5 m, unit flow of 21.4 cu.m.per sec., rated speed of 300 rpm and rated
output of 7,370 kW; The



7









 







coupled generator is of SF-K6300-20/3250 type with rated capacity of 7,000 kW and rated
voltage of 6.3 kV. The electrical equipment of the station is basically of 1980s’ products and the
electrical control parts are of traditional type.



1.3.3 Evaluation of the engineering




     (1) Scope of
installed capacity and generation volume



     As checked by our
 evaluation, the present installed capacity of the B.H.S. is 21,000 kW which
could reach an average annual generation of 13.815 million kWh according to an analysis of actual
generation during recent years.



     Comparing with the capacity scope of the up-stream stations under construction, the degree of
development of water resources of B.H.S. is comparatively low and installed capacity evidently
smaller. According to our inference based on relevant materials, the present reasonable installed
capacity should be over 44,500 kW with annual generation over 21.9 million kWh accordingly.



     (2) Main structures




     The site selection of the B.H.S. project is proper and general layout reasonable.



     The treatment of foundation of the head structures is correct. Both stability and strength of
the structures all have comparative big room. The construction quality of the head structures is
comparatively good, without defect, crack and leakage in appearance and no seepage in the
foundation.



     The alignment of channel and layout of head tank and penstock are reasonable and meet with the
flow capacity and requirement of operation set by the original design. The construction quality in
general is good and foundation stable without seepage phenomenon. But variation of flow situation
in the transition section of the channel is rather big causing a big local head loss.



     The foundation of the power house is of integrated and stable fresh rock. The layout of the
power house is reasonable and standard, meeting with the requirement of operation. The structures
all satisfy the requirement of stability and strength. The construction quality is fairly good, no
seepage and leakage emerged in the sub-structure part. The structure standard is rightly high and
operation environment good.



     In general, the B.H.S. has a reasonable design and good construction quality. Its head
structures has been keeping intact and complying with the operating performance of the original
design after 19 years operation. These structures are capable of continuous normal operation within
the life span given by the relevant codes if necessary normal maintenance could be kept.



     (3) Electro-mechanical equipment and metallic structures




     After change of the runner, the turbine efficiency is getting higher and flow capacity larger
and has attained the target of output increase with some big room. But the output of the unit is
still limited as the generator has not been replaced or thoroughly renovated and has only been
engaged with an on-site treatment of the



8









 







insulation for improvement of its performance. As per our investigation and analysis, the
rated output of the unit can only reach 7,000 kW.



     After renovation, the speed governor and excitation system can satisfy the requirement of unit
operation.



     The present electric main line has too much voltage levels and complicated relay protection
connection. The transformer is of out-of-date product. All these should be renovated and replaced
at appropriate time.



     The electric 2nd line control equipment is still of traditional type. It is
recommended that renovation be carried out for the 2nd line control and programmable
logic control (PLC) be used for automatic supervisory control of the units and reducing the
attendants. For protection equipment, micro-computer based facilities should be used to raise the
reliability of operation.



     For metallic structures, there are gates, trash rack and relevant hoisting devices which are
basically normal for the moment and could satisfy normal operation if routine maintenance work
keeps normal.



1.3.4 Development prospect




     (1) Power development plan



     In Dehong prefecture, hydropower resources are rich with a theoretical hydro-energy potential
of 3.624 million kW. The development condition is also very good. Under the guidance of the
national policy of western development and provincial policy of accelerating hydropower
developmeent, a high tide of hydropower development has been emerged in the whole prefecture. Most
of the schemed projects could be put into commission during the “Eleventh Five-Year Plan”. The
tendency of power source construction will keep well.



     It is planned that by 2010, there will be 123 hydropower stations with a total installed
capacity of 2.79 million kW and generation volume of 1,100 million kWh. Up to 2010, the consumption
load in Dehong prefecture will reach 770,000 kW with energy volume of 4,500 million kWh.



     The analysis of power and energy balance shows that in 2010, the maximum surplus power in
flood period in the whole prefecture will reach 2.30 million kW approximately and annual surplus
energy reach about 6500 million kWh. These surpluses will be exported under whole province’s
balance for supporting both the power growth in the province and the “West-East electricity
transmission” project.



     For improving the situation of “ no ability to send electricity out “ in flood period and
“shortage of electricity “ in dry period in Dehong prefecture, the local grid of the prefecture was
integrated into the Yunnan provincial grid in August, 2005. The Yunnan Grid Co. set up a Dehong
Branch Co. responsible for grid construction in the prefecture. During the “11th
Five-Year”, Yunnan Grid Co. will plan and construct 1 substation of 500 kV , 6 substations of 220
kV, 2 substations of 110 kV and relevant transmission lines in Dehong prefecture with a total
capital investment of 4,400 million Yuan for the grid construction. One of



9









 







the above projects is the Tailong 220 kV transmission and transformation project, about 5 km
from the B.H.S. which, after completion will be conducive to send out electricity from the Station.



     (2) Favorable effect from the “West-East electricity transmission “ project




     For implementation of the national strategy of western development and west-east electricity
transmission and realization of optimized dispose of regional resources, it is planned that during
the “11th Five-Year”, an additional amount of west electricity of 11.5-13.5 million kW
will be transmitted to Guandong province, in which 4.2-6.2 million kW will be from Yunnan.



     According to the plan, the +800 kV super high voltage D.C. transmission line from Yunnan to
Guandong is the main transmission channel of exporting Yunnan electricity to Guandong. Along with
the continuous construction of the “West-East electricity transmission” engineering, the situation
of no ability to send electricity out will no longer be happened to the B.H.S.



     (3) Regulation of off-take electricity price




     Currently, the off-take price of electricity to the grid in the region where the B.H.S. is
located and even in the Yunnan province is the lowest one in the Southern Grid. It is predicable
that this off-take price of electricity will have more space of inflation under the macro situation
of pushing forward of the national strategy of western development, accelerated growth of the local
economy, improvement of the channel of west-east electricity transmission project and deepening
institutional reform of the electric power sector as well as implementation of the << Law of
Renewable Energy >>.



     (4) Regulation function of the up-stream cascade reservoirs




     On the up-stream of the B.H.S. it is planned to construct 2 reservoirs and 7 hydropower
stations, in which the Sancahe reservoir has a total volume of 206 million cubic m and the
Sujiahekou reservoir has a total volume of 226 million cu.m. In addition, the Mennai hydropower
station also has a daily regulated reservoir of 2.09 million cu.m. After completion of these 3
up-stream reservoirs, the B.H.S. has an equivalent reservoir with volume coefficient of 8%, and the
capability of regulation could thus be greatly raised. The annual generation could have an increase
of 20 million kWh as per present scope of installed capacity. The average annual generation could
even increase more than 31 million kWh if the utilizing flow of the B.H.S. could comply with the
discharge from the up-stream stations.



     (5) 2nd phase expansion engineering of the B.H.S.




     The B.H.S. has a lower degree of development of water resources in comparison with the scope
of installed capacity of the up-stream stations under construction. For fully utilizing the
hydropower resources in the B.H.S., the Institute of Water Resource and Hydropower Surveying and
Design of Longqun Municipality, Zhejiang Province has prepared the << Pre-Feasibility Study
Report for Renovation and Expansion Engineering of the B.H.S. in Dehong Prefecture, Zhejiang
Province >> as entrusted by the Huabang Co. in 2005, and



10









 







submitted the scheme of construction of a new station on the right bank of the river for the
2nd expansion project.



     The structures of the new station will be laid out alongside the right bank, which compose of
the in-take, sluice gate, diversion tunnel, surge tank, penstock, power house and step-up
sub-station. The in-take of the new station is located at the right bank side of the existing
spilling weir and the power house on the opposite bank side up-stream of the existing power house.



     For the hydro turbine, type HLF13-LJ-190 is preliminarily selected, which has a design head of
38.5m and a rated flow of 30 cu.m./sec; the coupled generator is of SF10-22/4250 type with a rated
output of 10,000 kW.



     The designed static capital investment for the project is estimated to be 49.6 million Yuan
and overall construction period of 15 months.



     The 2nd phase expansion engineering of the B.H.S. has been confirmed through
registration for record in the Development and Reform Commission of Dehong Prefecture in January,
2006 (refer to the document DFGTG 75-2006).



     Our recommendation is that the new power station of the expansion project of the B.H.S. should
have an installed capacity of 2x12,000 kW and the grand total installed capacity of the B.H.S.
after expansion will be 45,000 kW with corresponding annual generation of 220 million kWh which
could further reach 250.6 million kWh if counting into the regulation function of the 3 up-stream
reservoirs. The estimated total static investment would be 78 million Yuan.



1.3.5 Economic evaluation




     Procuring the B.H.S. with 175 million Yuan and further put in 78 million Yuan for the
2nd phase expansion engineering, a total installed capacity of 45,000 kW could be
obtained with average annual generation of 241 million kWh.



1.3.6 Conclusion of the evaluation




     (1) As justified by this evaluation, the present total installed capacity of the
B.H.S. is 21,000 kW with average annual generation of 138.15 million kWh.



     (2) According to our consultation of the drawings and site investigation, it is recognized
that the B.H.S. in general, has a reasonable design and good construction quality of structures.
The hydraulic engineering structures of the Station still keep intact complying with the original
designed function for operation after 19 years operation. The structure of the project can keep its
normal continuous operation within the life span set by relevant norms only if necessary routine
maintenance work is conducted.



     (3) The existing electro-mechanical equipment is basically of 1986’s products when the station
was constructed. It is in general out-of-date although a part of the equipment has been renovated.
The 2nd line control equipment is still of traditional mode with only d.c. system
renovated.



     According the status quo of the electro-mechanical equipment, turbines, generators, excitation
systems and speed governors could still be used for



11









 







normal operation for over 10 years except that part of the electrical facilities is
recommended to be replaced.



     The metallic structure is basically in good condition and can satisfy normal operation only if
routine maintenance work could be kept.



     (4) In comparison with the utilization factor of hydro resources in the up-stream stations
under construction, the installed capacity of the B.H.S. is evidently on the smaller side and has a
fairly large potential for expansion. According to the topographical and geological condition, the
expansion scheme of building a new station on the right bank is feasible. It is therefore
recommended to make the new station on the right bank an installed capacity of 24,000 kW with an
estimated static total capital investment of 78 million Yuan.



     (5) The investment of the right bank new station is economical with a higher off-take price of
electricity and thus a better benefit. The financial evaluation for the old and new stations
together shows that the static turn back period is 7.64 years and that the financial indices are
optimal.



     (6) At present, the off-take price of electricity in the region where B.H.S. is
located and even in the whole Yunnan province is the lowest one in the Southern Grid due to
constraints of low local economic development and impedance of west-east electricity transmission
channel. But the benefit of the B.H.S. will be getting better in consideration of long term
development as there is a big room for inflation of the off-take price.



     Wrapping up the above-stated, the B.H.S. is basically complete and good. Its 2nd
phase expansion engineering has a high value of investment. The general economic indices for the
present stage are comparatively good and the prospect is promising. Therefore the evaluation of the
project is feasible.



2 General of Basin Planning




2.1 General Description of the Basin



Binglang river refers to the upper reach of Daying river, the grade-one tributary of Ayeyarwady.
It originates from Guyongjian mountain in Tengchong county, Yunnan, and its upstream is called
Dacha river and got the name of Binglang after pouring into Danzha river in Tengchong. Near the
old downtown of Yingjiang county, it joins Nandi river, and hereafter called Daying river. Daying
river flows through Gongbeng estuary to Burma, and then converges into Ayeyarwady river. Binglang
river extends about 120.2km, and the catchment area above its estuary is 2310.69km2, and
the mean annual flow is 128 m3/s at the converging with Nandi river.




     The Binglang river basin shapes as a fan, with the average elevation of 1831m above sea level.
The upstream valley is narrow with steep slopes and



12









 







rapids. The gradient averages 43‰ from Maguo river to Songshan estuary and even 68‰ in some
areas. After Songshan estuary river course becomes narrow or wide alternatively, and relatively
narrower from Songshan estuary to Zhila estuary with the average gradient of 5‰. Near Lesser
Menglong village, the river after Zhila estuary flows out of the gorge and enters Zhanxi plain and
water flows smoothly. The average gradient between Zhila estuary and Jianshan village at the
downstream of Mangzhang is 2.5‰. Since Mangzhang, Binglang river flows into gorgeable regions
again, and the river valley becomes asymmetric. The slope at east bank is relatively gentle, but
the west bank is steep with lots of cliffs and rapids. The average gradient of is 5.4‰ from the
foot of Jianshan village to Binglang river power station, but relatively larger at some parts. The
gradient from Binglang station to the converging of Nandi river averages 0.9‰, and water flows
smoothly again and both banks are mostly covered by vegetation. The original source of Binglang
river basin is at an elevation of 2000m, and the elevation of the converging with Nandi river is
837m above sea level, so there is a natural fall of 1200m or so, and the average gradient is 10‰
more.



     The slopes of Binglang river basin are well protected by vegetation and mainly covered with
subtropical broadleaf and shrubs, and the forest coverage amounts to over 90%. The silt content
inside river is not heavy, the water & soil erosion is slight and water quality of the river basin
is quite good. Owing to activities of ground critters, the ground and underground water is quite a
lot, and there is no flow cutoff in river. The riverbed is laid with rocks, and in dry sea there
is little suspensible silt and sediment is mainly from the flood season. Since 2005 some cascade
hydropower stations have been put under construction at the upper and middle reaches of Binglang
river, so water and soil erosion becomes worse, but this situation will not exist any more after
the completion of these hydropower stations.



2.2 Hydrology



Binglang river basin is located west to Higher Ligong mountain, which belongs to the tropical &
subtropical monsoon climate area with humid feature, and in summer it is affected by the monsoon
from southwestern side, so precipitation is rather plentiful in that period. Owing to crisscross
mountain ranges and different elevations, a complicated and changeable weather takes a shape, and
also the climate changes vertically. The climate factor changes with the altitude, temperature
increases from north to south, and precipitation decreases from north to south, and from high
altitude to low altitude. According to the data of Yingjiang weather station, the mean annual
temperature is 19.3oC, the ultrahigh temperature is 36.8oC (June 25, 1961) and the minimum is
-1.2oC (January 31, 1964). The annual mean evaporation (20cm) is 1907.0mm and mean annual
precipitation amounts to 1522.7mm. There is no much change


13









 






about rainfall year to year, but affected by climate, the annual rainfall is unevenly distributed,
i.e. there is a little during dry season (from November to the next April), about 15% of the whole
year, and during flood season (from May to October) it falls much, up to 85% of the annual
precipitation.




     Runoff in the basin mainly attributes to rainfall and a little amount of melted snow. This
basin has lots of rain, resulting in perfect vegetation and abundant underground water, and this is
a watery area with reliable sources. The runoff is consistent with the overyear change and annual
distribution of precipitation. According to statistics of Zhanxi hydrological gage station at
upstream which controls a catchment of 1548km2, the mean annual flow there is measured
90.8 m3/s and the mean annual runoff depth is 1849.8mm. The maximum annual mean flow is
124 m3/s (in 1966), which is proportioned to the mean annual flow as 1.37. The minimum
annual mean flow is measured at 64.7 m3/s (in 1978), which is proportioned to the mean
annual flow as 0.713. The ratio between the measured maximum annual mean flow and the minimum
maximum annual mean flow is 1.92. Therefore, there is no much difference among these ratio values,
which illustrates that the runoff in Binglang basin is stable, and the overyear runoff is not
changed too much. However, the annual runoff is unevenly distributed, and there is an evident
change between dry season and flooding season, i.e., during June-October it is 73.9% of the total
runoff, mostly concentrated in June-September, about 50.5%.



     The flood in the basin attributes to stormy rain, because during June-October, the oceanic
anticyclone of Pacific moves northwards and extends to west, and there is also high & low vortex,
and warm and humid airflow comes from southwest frequently, thus bringing about lots of vapor into
the inland. So this basin is affected, which results in frequent and strong rainstorm, and the
storm is mostly regional. The flood occurrence echoes the rainfall period. Because of frequent &
heavy storm, and steep slope & river course, flood increases and decreases swiftly, and the flood
is featured by hilly river there. It does not change much from year to year, and the maximum flood
peak mostly happens during June-August.



2.3 Planning & Development of Cascade Hydropower Stations



Binglang river has a total length of 120.2km, the catchment above the estuary is
2310.69km2 and the natural fall is about 1200m, so it ranks one of the medium-sized
rivers with pretty abundant hydropower resources in Yunnan province. Since the river flows through
Baoshan city and Dehong prefecture, hydropower resources is developed with regard to the planning
of these 2 regions respectively. Based on “Hydropower Planning Report on Binglang River (Danzha to
Songshan estuary)” compiled by Baoshan city, “Hydropower Planning Report on Binglang River (Dehong
part)” of Dehong and the planning drafted recently, two reservoirs encompassing 9 cascade
hydropower stations are


14









 






planned for construction on the main reach of Binglang river with a total installed capacity of
666.9 MW, among which, two reservoirs and four cascades at upstream belong to Baoshan city, and the
following 5 cascades are in jurisdiction of Dehong prefecture. From upwards to downwards, these 2
reservoirs and 9 cascades are respectively:




     Cascade one: Sancha river reservoir station—the normal storage level is 1890m, the total
reservoir storage 206 million m3 and the installed capacity totals 72 MW.



     Cascade two: Houqiao station—the normal storage level is 1719m, the total reservoir storage
770,000 m3 and the installed capacity totals 48 MW.



     Cascade three: Sujia estuary reservoir station—the normal storage level is 1590m, the total
reservoir storage 226 million m3 and the installed capacity totals 240 MW.



     Cascade four: Songshan estuary station—the normal storage level is 1243m, the total reservoir
storage 540,000 m3 and the installed capacity totals 168 MW.



     Cascade five: Mengnai station—the normal storage level is 1055m, the total reservoir storage
9 million m3 and the installed capacity totals 22 MW.



     Cascade six: Langwai river station—the normal storage level is 983.6m, the total reservoir
storage 5 million m3 and the installed capacity totals 45 MW.



     Cascade seven: Tucang station—the normal storage level is 932.8m, the total reservoir storage
4.8 million m3 and the installed capacity totals 38 MW.



     Cascade eight: Binglang river station—the normal storage level is 884.16m, the total
reservoir storage 120,000 m3 and the installed capacity totals 23.4 MW.



     Cascade nine: Mangkang station—the normal storage level is 831.5m, the total reservoir
storage is 2.22 million m3 and the installed capacity totals 10.5 MW.



     Among the above-mentioned stations, Binglang river station and Houqiao station have already
been completed, and meanwhile, Sujia estuary reservoir station, Songshan estuary station, Mengnai
station, Langwai river station, Tucang station and Mangkang station are under construction. Among
which, Sujia estuary reservoir station and Songshan estuary station plan to complete in 2010, and
others will be finished in 2007. The preliminary design has been finished for Sancha river
reservoir station.



3. Status Quo of Binglang River Station



Binglang River Hydropower Station, a diversion type, is located Xingba village, Xincheng township
of Yingjiang county, Dehong prefecture, which is 150km far from Mang city, the capital of Dehong,
Yunnan. The construction is started from April 1985 and completed in June 1988. The main
electromechanical


15









 






equipment has been rehabilitated in 2005 and 2006.




3.1 Hydrological Condition



The catchment area above the dam site of Binglang river station covers 2160km2, and it
has the general characteristics of aforesaid basin. According to the feasibility study report on
Tucang station, the mean annual precipitation in the basin is re-checked, as 2380mm, the mean
annual flow 123 m3/s, and the annual mean runoff is 3879 million m3. The
peak flow of design flood with a cycle of 50 years is 2955m3/s, and the peak flow of
check flood with a cycle of 300 years is 3901 m3/s.




3.2 Geological Condition



The geological constitution is relatively sophisticated in this region, and the lithosphere moves
frequently, therefore earthquake there is also active and the basic seismic intensity is Grade 8.




     Since the vegetation upstream is fairly good, and granite and metamorphic rock develop with
joints, as to keep water flowing through crannies, all the ditches along river banks always have
water flows even during a long-term dry season, and farmlands can be irrigated without any drought.



     The banks at dam site are unsymmetrical, i.e. the left side is a gentle slope and there is a
smooth ground at the foot, and the right bank is a steep cliff with height of 400m that is densely
forested. The mainstream of the original river is closely near the steep cliff at the right bank,
with the first terrace of 180m in width. The riverbed surface is covered with large boulders, and
then follows gravels with a thickness of 4~9m. The benchland surface at left bank is filemot soil,
and under that, is gravel soil with a thickness of 10~13m. At the steep cliff of right bank is a
strip of chorismite, open to air. The steep cliff and the riverbed at right bank, and the lower
benchland of left bank are both made of chorismite that contains hard and complete quartz and
feldspar quartz.



     The channel is arranged along the left bank, mostly on the smooth terrace, and a part goes
through the slope of exposed chorismite.



     The forebay is located on the second terrace, and owing to the branches crossing, the terrace
has topographical waves, and it is also a man-made terrace, therefore it is rather complicated.
The surface is covered with soil suitable for crops plantation, and then mostly comes the densely
eroded soil from granite with a thickness of 12~18m. The lower base rock is the mixed granite.



     The powerhouse is situated behind the first terrace and close to river, with a slope of about
25o, and near water there is mixed granite exposed to air, along with large boulders.
Above the flood level, there is covered with boulder soil with a thickness of 3~8m, and after that,
the base rock is the mixed granite too.

     Basically in the powerhouse, electromechanical equipment is still the ones installed in 1986
and made by Hangzhou Electric Equipment Works, but some parts are technically rehabilitated. In
1999 three governors are renovated, that is, the PLC microcomputer-based governors replace the old
mechanical ones. During 2005-2006, three turbines are renovated, and with the replacement of new
runners, the unit capacity is increased from 6300kW to 7000kW. Meanwhile, the generator and the
excitation system are also rehabilitated, and the flow passage of turbine, including spiral case,
draft tube and distributor, is not changed. There is also no change about the civil works of
powerhouse.

4.1 Installed Capacity and Power Generation



Before 2000, county grids in Dehong prefecture are not integrated into prefecture grid, and B.H.S.
mainly supplies electric power to Yingjiang, Lianghe and Luxi counties, occupying a very low load
in power system. For instance, in 1982 the total installed capacity inside the system is 11.7 MW,
and the yearly generation is 24,760 MWh, therefore with an installed capacity of 18.9MW, the
generation capability of Binglang river hydropower station is not fully utilized. After all the
grids of whole prefecture is integrated together in 2000, the station can only be put into its
normal operation with the flow from upstream. Table 4-1 refers to the actual yearly power
generation after grid integration of the whole prefecture.




     Table 4-1 Actual yearly power generation of B.H.S.



	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 	 
	Year	 	2001	 	2002	 	2003	 	2004	 	2005	 	2006
	Generation
(103kWh)
	 	 	90080	 	 	 	117030	 	 	 	115910	 	 	 	120850	 	 	 	122570	 	 	 	110930	 






     After technical rehabilitation in 2005 and 2006, the installed capacity of B.H.S. is 3×7000kW,
and the designed mean annual generation amounts to 138.15 million kWh. If the effective power
coefficient considers at 0.95, the effective yearly generation is 131.24 million kWh, 6.6% over the
actual generation in 2005 and 15.5% more than that of 2006. Since year 2006 is a relatively dry
season, it sounds reasonable to have the designed mean annual generation of 138.15 million kWh.



     According to the load demand at that time, the installed capacity of B.H.S. is initially 18900
kW, and although increased to 21000 kW after rehabilitation, the yearly utilization hour is still
as high as 5904h, so hydro resources is not fully developed and utilized. However, with
foreseeable increase of off-take tariff and completion of large-sized reservoirs upstream, this
situation would be changed. At present, the yearly utilization hours of upstream stations under
construction are averaged at 5000h, and the installed capacity of B.H.S. is evidently small, and
the flow from upstream stations is not fully used for power generation. According to the scale of
Tucang station, the suitable installed capacity of B.H.S. is deemed to be over 44.5 MW at present,
and correspondingly, its yearly generation would amount to more than 219 million kWh.



     4.2 Main Structure



29









 





4.2.1 Headwork




     The layout diagram of headwork shows a reasonable general arrangement. Though the maximum dam
height is up to 13.2m, actually the maximum water-level difference between upstream and downstream
of overflow dam is only 8m. The cross section of overflow dam is designed relatively solid, and
the thickness of concrete above the cement rubble is up to 2m. Other structures are also
relatively large-sized, and furthermore, most of the structures are based on rocks. Therefore, the
structure of headwork is stable and strong enough.



     On-site checking finds the construction quality of headwork structure is rather high, and no
failure, crack or leakage are found on the surface, especially no leaking on the foundation, only
except a little arising from the aged water stop of scouring sluice. Besides, the construction of
upstream hydropower station leads to heavy silt content in water and serious sediment before the
dam. There is also superficial erosion owing to a long-term overflow on the weir.



     Meanwhile, it is mentioned there needs a large flow for generation after the technical
rehabilitation, but in case of extra overflow on the weir, water flow into the channel is still
insufficient, which restricts a full output of the station. After perusing the drawings and
surveying the site, it is found the channel intake is not able to pass sufficient flow, which is
the main reason for output restriction. After calculation, the issue is checked again, finding
that if the intake is unchanged, it is impossible to pass the design flow of 60 m3/s at
the normal storage level 834.156m, because the bottom elevation of intake gate is too high. If the
proposal of Huabang Company is adopted, i.e. 0.5m is increased for the overflow weir, this issue
can be addressed.



4.2.2 Diversion channel, pressure forebay and penstock




     The drawing of diversion channel also shows a reasonable arrangement, and the channel lining
is solid, stable and endurable, and its passage capability is sufficient.



     After checked from headwork to forebay by walk, the general construction is found in a good
quality, the upper side-slope of channel is stable, and there is no collapse or leakage, only
except partial break of cement mortar on the sidewall surface. Since it crosses several different
sections and slopes, the flow regime at the transition part changes much, resulting in partial loss
of water head.



     At the penstock inlet, the forebay foundation is relatively poor, so measures have been taken
to reinforce during construction. The geological condition of other foundations is fairly good.
In general, the construction quality is acceptable, and there is no collapse or leaking, and it can
meet the requirement of normal operation.



     The penstock is suitably arranged with stable foundation. There is only a little leaking from
the extension joint, on the top end of 3# penstock.




30












 





4.2.3 Powerhouse




     As per the layout drawing, the foundation of powerhouse is on complete and fresh rocks, and
its arrangement sounds reasonable, standardized, stable and strong enough, and it can meet the
operating requirement. Floodwalls are erected for both powerhouse and plant area, and the
flood-prevention requirement can be met.



     After site checking, there found no leakage on the structure under water, the construction
quality is good, and a high standard is applied. The generator floor is naturally bright and
ventilated, and even on the turbine floor, it is clean and bright, and kept in a good order, so the
operation environment looks nice.



     B.H.S. is invested with state fund and managed by the government. It is designed by Kunming
Hydroelectric Investigation, Design and Research Institute, and constructed by professional
contractors, so its design, construction and management is standardized. Generally speaking, the
design of B.H.S. is rational and the construction quality is quite good. Although it has been in
operation for 19 years, the structure is still kept perfect and can meet the operating function.
As long as necessary daily maintenance & management is undertaken, hydraulic works can continuously
be in a normal operation for its whole service life as specified by the standard.



     According to calculation, the suction height of new runner is 2.3m, so if the condition is
available, the downstream riverbed can be dredged as to reduce the tail-water level and
simultaneously increase the head for increasing power generation.



4.3 Electro-mechanical Part




4.3.1 Turbine




     In 2005 and 2006, new runners are applied for turbines, and the efficiency of new runner is
higher because the flow passing through turbine is larger and it can meet the requirement of output
increase. At the design head of 38.5m, the turbine operates in a high efficiency zone, and within
the head of 36-42m, the unit also can operate efficiently. When the unit operates in a low-head
zone, the efficiency can only be high in case of a large flow, vise versa. Therefore, the flow
should be increased when operating in a low-head zone.



     The cavitation coefficient of new runner is small and according to calculation, the suction
height of new runner is 2.3m under the rated working condition, and if possible, the tail-water
level can be decreased as to increase the water head for more power generation.



4.3.2 Generator




     According to the feasibility study report on technical rehabilitation, the axial output of
turbine is requested to be 8125 kW after changing for new runners, so it needs to use one set of
SF8000-20/3250 type generator with the



31









 




rated capacity of 7800 kW. However, during the technical rehabilitation in 2005~2006, the
generator is not replaced or renovated thoroughly, only except its insulation performance is
improved on site, but it still cannot withstand a larger current, so the rated capacity cannot be
increased more.




     As
checked at site, the output of unit 1# and 3# is 6700kW and all the indices are quite
normal. By consulting the operation record, it shows the maximum active power output is 7300kW,
but the reactive power is only 2200kVAR, which indicates a space for more turbine output. So it is
presumed that, when the power factor is decreased, the rated unit output of 7000 kW can be
guaranteed.



     There is no data or information about the generator rehabilitation, so we cannot make any
conclusion. But the generator current exceeds its rated value, so its safety cannot be ensured.
Therefore, in order to restrict stator current, the station can only sacrifice reactive power and
generate more active power during its actual operation.



4.3.3 Governor




     After rehabilitation, the governor can meet the operating requirement, but there is leaking on
the servomotor.



     Regulation guarantee is calculated after renovation, and owing to the limit of increased flow,
capacity is not much increased. Therefore, the closing time of guide vane is adjusted, and the
station facilities can meet the demand of regulating guarantee.



4.3.4 Excitation system




     After rehabilitation, the excitation system can meet the operating requirement.



4.3.5 Main electrical wiring




     Presently, the main electrical wiring involves many voltage grades, large space for equipment
arranging and complex relay protection, so it needs to be rectified in due course.



4.3.6 Main transformer




     Unequal impedance voltage between high & middle voltages of two main transformers would lead
to circumfluence between 35kV and 110kV busbars, so the stepping-up substation needs to be
renovated as to avoid this problem. The transformer is outdated, leading to a big power loss, and
the series 6 and 7-type transformers as the early products, cannot be used any more.



4.3.7 Secondary electrical part




     Control equipment of secondary electrical part still adopts the conventional mode, which is
not beneficial to management and rational utilization of water, and the regulating property is also
poor. The data of upstream & downstream



32









 




water levels cannot be automatically transmitted to the central control room, so the central
control room cannot acquire the water level information timely.




     It is suggested to rehabilitate the secondary electrical part, in which the programmable logic
controller (PLC) can be applied, as to achieve an automatic monitoring and control, as well as
reduce operating staffs. The protection device can adopt microcomputer-based type to improve the
reliability of equipment protection and operation.



4.4 Metal Structure




Metal structure of B.H.S. consists of gate, trash rack and headstock gear, which all are well
maintained, and they can still meet the normal operating requirement only if daily maintenance
needed.



4.5 Environmental Re-assessment




B.H.S. is a diversion type built with a low dam, and it’s completed 3 years before and in operation
for 19 years, so the surroundings has already been in a stable situation, and the vegetation has
been protected and recovered from the construction impact.



     Recently, the construction of upstream hydropower stations has resulted in heavy silt content
in water and a serious sedimentation before the dam of Binglang station, but this would be improved
after these stations completed.



     The barrage cuts off water flow for river section to the powerhouse side, so ecological
environment of this part will be certainly impacted, especially on fish. But this would not
threaten the production and living used water at both banks, because there is no habitant or arable
land at the right bank, whilst the right bank area is conveniently irrigated with water from the
diversion channel.



5. Development Prospect




5.1 Planning of Local Power Development




Dehong prefecture is very abundant in hydropower resources, with a theoretical hydro energy
potential up to 3.624 GW, and exploiting conditions are very good. Encouraged by the Western
Development Drive and provincial policies in regard of hydropower exploration, the whole prefecture
is heated with hydropower development presently, and most of the hydropower stations will be put
into operation during the “11th Five-year Plan” period.



     By the end of 2006, there are 68 hydropower stations in Dehong with a total installed capacity
of 491.866 MW, among which, 63 stations with a total



33









 




capacity of 292.866 MW are dispatched by Dehong Electric Power Holding Co., and another five
stations with a total installed capacity of 199 MW dispatched by Dehong Sub-company, Provincial
Power Grid Company of Yunnan. By 2010, totally 123 hydropower stations can be expected in Dehong,
with installed capacity of 2.79 GW and power generation of 11 billion kWh. Among which, Dehong
Electric Power Holding Co. Ltd. will dispatch 82 stations with installed capacity of 650 MW and
generation of 3 billion kWh, whilst Dehong Sub-company, Provincial Power Grid Company of Yunnan
will dispatch 41 stations with a total installed capacity of 2.14 GW and generation of 8 billion
kWh.




     Now the maximum load in the whole Dehong prefecture totals 260 MW, the minimum is 180 MW, and
the average load is 240 MW. Among which, 60% of total power in the area is consumed by the silicon
mineral smelting industry, and in 2007 Zhuoxin silicon smelting factory (with capacity of 7.5 MW)
and Mangshi silicon smelting factory (with capacity of 25 MW) will be built up. The installed
capacity of stations dispatched by Dehong Electric Power Holding Co. is 292.866 MW by the end of
2006, and predicted to be 343.146 MW at the end of 2007, and by 2010 it can be up to 650 MW.
According to yearly increase of power consumed and construction of industrial parks in counties or
cities, it is predicted in recent years, Dehong prefecture still needs part of electric power from
provincial grid to meet the local demand, and by 2010 the power load will be up to 770 MW and the
yearly power consumption will be 4.5 billion kWh in Dehong. Besides the generation of 3 billion
kWh power dispatched by Dehong Electric Power Holding Co. Ltd., 1.5 billion kWh needs to be
supplied by the provincial grid as to meet the local power demand.



     However, a general analysis on electric power & quantity balancing shows, in 2010 the maximum
power surplus is about 2.3 million kW in flood season in the whole prefecture, and the power
surplus of the whole year will be about 6.5 billion kWh that shall be sent out for balancing in the
whole province. This can greatly boost the power increase of the whole province and support the
west-to-east power supply strategy, and turn hydro-energy resource advantage into economy
advantage, thus promoting the local economy of Dehong.



     In order to send out surplus power in flood season and alleviate power shortage in dry season,
in August 2005 the grid of Dehong prefecture is integrated into the provincial grid of Yunnan, and
Provincial Power Grid Company of Yunnan sets up its Dehong Sub-company which is mainly responsible
for grid construction in the region. At present, the power grid in Dehong prefecture is jointly
managed by Yunnan Dehong Electric Power Holding Co., Ltd. and Dehong Sub-company, Provincial Power
Grid Company of Yunnan. According to the agreement signed between Dehong Electric Power Holding
Co., Ltd. and Provincial Power Grid Company of Yunnan, the electric power dispatched by Dehong
prefecture shall be firstly used to meet the



34









 




local demand, and then surplus power be transmitted outside through the provincial grid,
hereby Provincial Power Grid Company of Yunnan charges 0.02RMB Yuan/kWh for use of the grid. The
power of stations under Provincial Power Grid Company shall be transmitted to provincial grid
through 550kV and 220kV lines for outside use. According to the signed “Agreement on Grid
Dispatching and Management Scope in Dehong Prefecture”, it is clarified, with the principle of
overall planning & dispatching management, the grid integration of stations newly built in the
basin of Binglang river, Mengjia river, Mengnai river, Daying river and Longjiang river shall be
managed by Yunnan Provincial Grid Company according to the related stipulations about grid
connection, as well as the proposal of interconnecting system.




     Once integrated into the provincial grid, the awkWard situation has changed completely, and
now there are two substations operated by Dehong Sub-company, Provincial Power Grid Company of
Yunnan, i.e. 220kV Luxi substation and 220kV Yingjiang substation. As per the “11th
Five-Year Plan” of Provincial Power Grid Company of Yunnan, one 500kV substation, six 220kV
substations, two 110kV substations, 560km-long 500kV transmission line, 680km-long 220kV
transmission line and 170km-long 110kV transmission line shall be planned and constructed in
Dehong, with a total investment of 4.4 billion RMB Yuan for grid construction. Among which, under
construction is 220kV Dailong dispatching & substation works, about 5km away from B.H.S., and
planned in operation in June 2007, subsequently a 5km-long 110kV transmission line will be erected
to interconnect B.H.S. to the 220kV Dailong substation, thus facilitating the power transmission of
Binglang station to outside.



     By the end of 2006, there have been built and operated eleven 110kV substations with a total
capacity of 308.5 MVA, twenty-one 110kV transmission lines with a total length of 768km, two 220kV
substations with total capacity of 360 MVA and a 225km-long transmission line of 220kV in Dehong
prefecture.



     As predicted, there will be fourteen 110kV substations with a total capacity up to 694.5 MVA
and 940km-long 110kV transmission line by the end of 2008 in Dehong, and the 110kV dual-loop line
can transmit 360 MW power. Furthermore, there is to be built five 220kV substations with a total
capacity of 1,800 MVA, 525km-long 220kV transmission line, and the 220kV grid can transmit an
electric power up to 620 MW. In 2010 a 550kV substation will be built up with its capacity of 1500
MVA, and the matched 550kV transmission line is up to 340km in Dehong. So in 2008, more surplus
power will be delivered to the provincial grid through 220kV and 550kV transmission lines.



5.2 Positive Results of West-to-East Power Supply




The southern power grid covers five provinces such as Guangdong, Guangxi, Yunnan, Guizhou and
Hainan with an area of about 1 million km2. The



35









 




unbalanced development of energy resource and economy between east China and west China becomes
especially conflicting in the aforesaid southern 5 provinces. The GDP of Guangdong province in the
east occupies 65% of the total 5 provinces, but its energy reserve is
only 3.5% of the total.
However, the economically underdeveloped Yunnan and Guizhou provinces total an energy reserve of
over 90% of the five, among which the exploitable installed capacity of hydro is up to 95.7 GW in
Yunnan. Therefore, it would be the only way to undertake the large-sized transmission of electric
power from west to east and to optimize the resource configuration for energy development in south
area.




     When the west-to-east power transmission of south grid is started in August 1993, there is
only one route with a capacity of 700 MW. After quick development in the past 5 years, there have
been set up nine 500kV transmission passages consisting of three D.C. lines and six A.C. lines from
west to east, with the transmission capability of over 12 GWh. During the “10th
Five-year Plan” period, an installed capacity of 8.11 GW has been put into operation in Guizhou and
the power supply to Guangdong maximizes 4 GW. In Yunnan, an installed capacity of 5.16 GW has been
put in operation and a maximum power supply to Guangdong is 1.6 GW. West-to-east power
transmission becomes a symbolic project of the Western Development Drive. From 1993 to 2006, the
annual supply of electric power from west to east in the southern grid is increased from 1540GWh to
6780GWh, totaling a 266,400GWh supply in that period.



     The west-to-east power transmission explores a huge market and gives a strong push to the
hydro-based power industry in Yunnan. During 1993-2005, the total installed capacity almost
triples in Yunnan. During the “10th Five-year Plan” period, RMB74.4 billion Yuan has
been invested into power industry as fixed assets, ranking the first in the province for the fixed
assets investment. The sales revenue of power industry is increased from RMB9.47 billion Yuan in
2000 to RMB30.06 billion Yuan in 2005, i.e. over doubled. The total tax rises from RMB2.12 billion
Yuan to RMB5.26 billion Yuan, 1.5 times.



     To further undertake Western Development Drive and west-to-east power transmission strategy as
to achieve a optimized configuration of regional resources, it is planned during the “11th
Five-year Plan” period, an increase of 11.5-13.5 GW power be supplied to Guangdong, among which, an
increase 4 GW is from Guizhou and 4.2-6.2 GW from Yunnan, 2.1 GW from Longtan hydropower station,
and 1.2 GW from Liyujiang power plant. In 2010 a maximum power of 22.4-24.4 GW will be supplied to
Guangdong.



     As planned, the southern grid shall give priority to build the power transmission projects
from Guizhou to Guangdong, from Yunnan to Guangdong, the sending-out of electric power from Longtan
hydropower station, and other west-to-east power transmission projects during the “11th
Five-year Plan” period. Among them, the ±800kV ultrahigh-voltage D.C. power transmission project
is



36









 




one of the main routes for power supply from Yunnan to Guangdong. After these projects
completed, the west-to-east power transmission will step onto a new higher stage.




     Therefore, with continuation of the west-to-east power-supply projects, the awkWard situation
won’t happen again that electric power of hydropower stations, including B.H.S. in the vast
southeast cannot be sent out, even if the hydropower development is presently at its climax.



5.3 Adjustment of off-take Tariff



For a long time, the off-take tariff of SHP in China is relatively low owing to historical and
institutional causes, and SHP off-take tariff of the most provinces is lower than the average
purchasing tariff in those areas. For example, the national average purchasing tariff in 2003 is
RMB0.326 Yuan/kWh, and the SHP off-take tariff to the national grid averages RMB0.263 Yuan/kWh, so
there is a difference of RMB0.063 Yuan/kWh. In 2004 and 2005 the power tariff has been regulated,
but in some provinces SHP off-take tariff is not adjusted accordingly, the difference becomes
larger between the national average power-purchasing tariff and the SHP off-take tariff. But
generally speaking, with the development of Chinese national economy and the conflict between power
supply & demand, SHP off-take tariff is gradually increased. For instance, the off-take tariff of
B.H.S. is initially RMB 0.15 Yuan/kWh in flood season and RMB0.20 Yuan/kWh in dry season, but now a
new tariff is applied for new stations under construction at upstream, up to RMB0.215 Yuan/kWh.




     Meanwhile, the off-take tariff differs from each other owing to imbalanced development of
economy in different regions. For example, in 2003 the average off-take tariff of Guangdong
province (also in the southern power grid) is RMB0.388 Yuan/kWh, but in Yunnan province it is
RMB0.155 Yuan/kWh. Presently, the off-take tariff in the region of B.H.S. and even Yunnan province
is the lowest in the southern power grid, this because the local economy is underdeveloped, and the
west-to-east power transmission is not smooth, so surplus electric power cannot be sent out timely.
It can be predicted, with the advancement of Western Development Drive, the local economy will see
a great leap, and the west-to-east power transmission will be much improved. With deepening of
power system reform and enforcement of “Renewable Energy Law”, there would be a large potential for
the rise of off-take tariff.



5.4 Storage Regulation of Upstream Cascade Reservoirs




At the upstream of B.H.S., there are two reservoirs and seven stations under planning, among which
Sancha river reservoir has a total storage of 206 million m3 and Sujia estuary reservoir
has a total storage of 226 million m3. Besides, there is a daily regulating reservoir
of 2.09 million m3 at Mengnai station, and



37









 




Mengnai station and Sujia estuary reservoir will be put into use respectively in 2007 and 2010, and
the upfront work has been completed for Sancha river reservoir, waiting for construction. After
these 3 reservoirs completed on the upstream of Binglang river, it seems to set up a reservoir with
a storage coefficient of 8% for B.H.S., thus the storage-regulating capability much improved.
Based on the present installed capacity, a mean annual power generation of about 20 million kWh can
be increased, and if the inflow of B.H.S. is well matched with the discharge from upstream
stations, a mean annual generation of over 31 million kWh can be increased.




5.5 Project Enlarging Potential and Proposal




5.5.1 Enlarging potential of B.H.S.




     The utilization hour of SHP installed capacity is an important dynamic index, which indicates
the development & utilization extent of hydropower resources. The utilization hour is mainly
determined by off-take tariff, and generally the higher the off-take tariff is, the lower the
utilization hour is. In China, the off-take tariff is established by different governments, and it
is closely related to local economic development and the energy (power) supply & demand, therefore
the off-take tariff and the utilization hour are both regional. Meanwhile, with unceasing
development of economy, the energy (power) supply and demand relations are different during various
periods, so the off-take tariff and the utilization hour also have their historical properties.
The utilization hour of stations built in early China is relatively high, but according to the
current knowledge, the resource is wasted to some degree, so these hydropower stations have huge
potentials for capacity enlarging. The same is B.H.S., and compared with upstream stations under
construction, its installed capacity is much smaller.



     With the expected rise of off-take tariff and the construction of large-sized reservoirs at
upstream, the installed capacity of B.H.S. seems evidently small, because the yearly utilization
hours of being-built upstream stations are all lower than 5000h, but that of B.H.S. is 5904h at
present. The present inflow of B.H.S. is 64 m3/s, however, the inflow of Tucang station
upstream is 141 m3/s, so there is mismatched between the inflow of B.H.S. and the
discharge of upstream stations. If estimated according to the scale of Tucang station, the
reasonable installed capacity of B.H.S. should be over 44.5 MW, and correspondingly its yearly
generation can be more than 219 GWh. If the storage-regulating role of three upstream reservoirs
is taken into account, its yearly generation can amount to 250 GWh more.



5.5.2 Second phase of capacity enlarging for B.H.S.



     To fully utilize the hydro resources of B.H.S., in 2005 Huabang company entrusts Longquan
Water Resources and Hydropower Investigation & Design Institute of Zhejiang Province to compile the
“Pre-feasibility Study Report on



38









 




the Capacity-enlarging Rehabilitation of Bingkang River Station in Dehong Prefecture of Yunnan
Province”, in which a proposal is put forward for building a new station at the right river bank
for enlarging the capacity as the second phase project.




     For the second phase of capacity-enlarging project, the new station is suggested to have an
installed capacity of 2×10MW and the designed mean annual generation can be increased by 79850 MWh
(the storage-regulating role of upstream 3 reservoirs is not considered).



     The hydraulic structure of new station will be arranged along the right bank, which is
composed of intake, scouring sluice, diversion tunnel, surge tank, penstock, powerhouse and
stepping-up substation etc. The normal storage level of the station is 884.16m, the tail water
level is 841.00m and the gross head is 43.16m.



     The overflow weir at the right bank shall be dismantled for the setup of an intake and a
scouring sluice, and the intake is followed with a channel, and then 1800m-long tunnel. The
excavation diameter of the tunnel is 6m, and it becomes 5.2m after lined by the reinforced
concrete. A surge tank is erected at the end of the tunnel, and after the surge tank built two
bifurcates which are connected to penstocks entering the powerhouse.



     The powerhouse is located at the upstream of old powerhouse, right bank of Binglang river.
The powerhouse is a kind above the ground, and the total building area of main and auxiliary
powerhouse amounts to 40m×20m. Inside the main powerhouse are arranged two sets of vertical-shaft
Francis turbine-generating sets, governors, main valves and the control cabinets and other
electro-mechanical equipment. In the auxiliary powerhouse there are central control room,
high-voltage switch cubicle and transformer room etc.



     The stepping-up substation is an outdoor type, arranged at the downstream side of powerhouse,
and the high-voltage side of main transformer is connected to the old substation at left bank
through the aerial line.



     The turbine initially adopts the type of HLF13-LJ-190, with the design head of 38.5m, rated
flow of 30 m3/s, and it shall be matched with the generator of SF10-22/4250, and the
rated power of generator is 10000kW.



     The main electrical wiring is an enlarged unit connection, i.e. two units shall be served by
one transformer with type of S11-25000/110, the high-voltage side of main transformer shall be
linked to the location of original 2# main transformer inside the old substation at the left bank
through the 110kV aerial line.



     As designed, the total static investment is estimated to RMB49.6 million Yuan, and the total
construction term is 15 months



     According to the design proposal, the investment estimate is probably low, because it is
estimate that the total static investment would be RMB65 million Yuan. Since these three
reservoirs have been completed at the upstream, a mean annual generation of 91 million kWh can be
increased.



39









 





     The capacity-enlarging project for B.H.S. has been registered to Dehong Development and Reform
Commission in Jan. 2006 (please see the document No. [2006] 75).



     If the installed capacity of new station for capacity enlarging is 2×10000kW, the total
installed capacity of B.H.S. will be 41 MW after that, still smaller than the aforesaid 44.500 MW.
Therefore it is suggested to set up the new station with the installed capacity of 2×12000kW, so
after enlarged, the total installed capacity of Binlang river station is 45000 kW.
Correspondingly, its yearly generation would amount to 220 GWh, and if three upstream reservoirs
perform their storage-regulating functions, the yearly generation will be 250.60 GWh. The total
static investment is estimated RMB78 million Yuan.



     In case that the output of old station is much affected by the tail-water level, so if the
powerhouse of new station is located at the upstream of old powerhouse, the downstream riverbed
needs to be dredged, otherwise, the output of old station will be restricted much more. Therefore,
it is proposed to further compare and verify the new powerhouse site and the diversion system at
the follow-up stage.



6 Economic Evaluation




6.1 General




Binglang River Hydropower Station has the sole purpose of power generation, with the installed
capacity of 21 MW and mean annual power generation 138.15 million kWh. To fully utilize the
hydropower potential, the second phase of capacity enlarging is to be implemented. The installed
capacity of the new station is 2x12000 kW and the designed mean annual power generation could
increase by 81.85 million kWh. In view of Sujiahekou and Mengnai reservoirs at the upper reach to
be completed soon, the annual power generation could be calculated as 241 million kWh within the
calculation period. As Sanchahe reservoir is not yet started, its increased benefit is thus not
considered temporarily.



     The economic evaluation for Binglang River Hydropower Station has been based on the current
tariff policies and regulations concerned.



6.2 Investment Plan




In the early first year, 175 million Yuan will be primarily invested to purchase Binglang River
Hydropower Station for the project. In the second year, 78 million Yuan will be input for capacity
enlarging of the Station as the second phase, the total construction period of which will be 15
months. For the



40









 




convenience of calculation, the construction period of the capacity enlarging is set as one year.




     The proportion of current capital for the Station is quite small and after the purchase, there
will soon be sale revenue for the old Station. So, the annual current capital is not counted here.



6.3 Basic figures




     (1) Amount of energy selling to the grid



     The amount of annual power generation for the Station is 138.15 million kWh in the first year
and 138.15 million kWh in the second year. Starting from the third year, the annual power
generation will be 241. million kWh.



     In accordance with the actual situation of B.H.S. in the recent years, the valid energy
parameter for B.H.S. is 0.95, station service power is 0.5% and the transformation and transmission
loss is 2.5%.



     (2) Generation revenue



     The financial evaluation for B.H.S. is made according to independent account as a power
generation item within the grid. Based on the related regulations in Yunnan province and Dehong
prefecture, the selling price to the grids for the old station is 0.15 Yuan/kWh in rainy season
(from June to Dec), 0.20 Yuan/kWh in dry season (from Jan to May). From the actual conditions in
the recent years for B.H.S., the comprehensive selling price to the grid is 0.16 Yuan/kWh for the
old station. The energy sold to the grid for the old Station is 127.32 million kWh, with annual
sale revenue 20.3712 million Yuan.



     The comprehensive selling price to the grid is 0.215 Yuan/kWh for the new station. The amount
sold to the grid is 94.79 million kWh for the new station with the total income 20.3795 million
Yuan.



     (3) Tax and additional tax



     • VAT



     According to the related regulations of Dehong prefecture, 6% as VAT from SHP generation
income is levied, which is 2.445 million Yuan.



     • Sale tax



     It includes city maintenance construction and education tax, levied according to the base of
VAT. They are 1% and 4% respectively. 0.03% from power generation income is imposed as the stamp
tax. The cost of this tax amounts to 134,500 Yuan.



     (4) The sale cost of the power generation



     It includes maintenance fee, staff wage and welfare, water resource fee, material fee, and
other expenses etc.



     1%of the total fixed asset is set as the maintenance fee. It is 1.75 million Yuan for the old
one and 780000 Yuan for the new one.



     Wage and welfare: There are currently 30 staffs for the old Station and the mean annual wage
12000 Yuan per person. Thus, the total amount of wage for the old station is 360000 Yuan. 14% of
the total wage is set as the welfare for



41









 




the staff and so the total welfare amount is 50400 Yuan for the old station. After
commissioning of the new station, there will totally 45 staff and the averaged annual wage 12000
Yuan per person. Thus, the total wage is 540000 Yuan. 14% of the total wage is set as the welfare
fee which is equal to 75600 Yuan.




     The water resource fee payable at 0.004 Yuan/kWh, it will be 509,300 Yuan for the old station
and 379,200 Yuan for the new one.



     The fixed material fee is at 5 Yuan/kW, it will be 105,000 Yuan for the old one and 120,000
Yuan for the new one.



     The
other expense is at 18 Yuan/kW, it is 509,300 Yuan for the old one
and 379,200 Yuan for
the new one.



     The sale cost of the power generation is 5.0691 million Yuan.



     (5) Income tax



     According to the agreement between Huabang Corp and local government in 2004, the income tax
in 2004 and 2006 is exempted. In 2007 and 2008, 7.5% as the income tax is levied. From 2009 and
onwards, 15% as the income tax is levied in accordance with the State’s policy to develop the west
area of China.



6.4 Evaluation Method



Calculation of return period of the static investment.




     The return period of the static investment refers to the ratio of total investment of the
project to the power generation income deducting the powwow generation sale cost, tax and addition
(namely VAT,+sale tax addition+stamp tax). After calculation, the return period of the static
investment is 7.64 years.



6.5 Evaluation Conclusions




     (1) Among those SHP stations of similar nature to be constructed in Yunnan province, this is a
more favorable project with ideal indexes to purchase Binglang River Hydropower Station for 175
million Yuan and input 78 million Yuan for the second phase capacity enlarging construction to
realize a total installed capacity 45 MW with a mean annual power generation 241 million kWh, 5622
Yuan investment per kW cost and 1.05 Yuan as unit energy investment.



     (2) Based on the calculation of comprehensive selling price 0.16 Yuan/kWh for the old station
and selling price 0.215 Yuan/kWh for the new station, the return period of the static investment is
7.64 years. The financial indexes are very good. In actual operation, as the new stations have
higher efficiency with higher selling price. Put the new station in priority to generate
electricity, then the financial indexes will be even better.



7. Appraisal Conclusions




42









 








     (1) Binglang River Hydropower Station, a diversion type, lies at Xinbazhai, Xincheng township,
Yunjiang county, Dehong Dai & Jinpo minorities autonomous prefecture of Yunnan province. The
Station started construction in April 1985 and was completed in June 1988. Technical refurbishment
was made in 2005 and 2006 for the main electric and mechanical equipment. After evaluation this
time, its installed capacity is currently 21 MW with mean annual power generation 138.15 million
kWh.



     (2) After checking the related drawings and site investigations, the layout of the total key
engineering of Binglang River Hydropower Station is reasonable. The design of all the key civil
works, except for the intake works and the open channel which have slight demerits, is rational.
The intensity and stability of all the structures are sufficient, with foundation treatment
satisfactory. The overall design could be rated as reasonable. The construction quality for the
civil works is also good. Although the Station has been operating for 19 years, the civil works of
the station appeared essentially sound, meeting the functional requirements of the original design,
and there are no salient defects, cracks or leakage. With some daily maintenance, the key civil
works could continue to operate normally within its life span.



     (3) In combination with the concrete situation of hydropower construction at that time, the
selection of the main electric mechanical equipment and the electric design are reasonable. The
main electric mechanical equipment belongs to that in 1986, but the technical refurbishment to some
part has been implemented. In 1999, the governor was replaced with a micro PLC, new runners were
mounted in 2005 and 2006 respectively to the turbines, insulation of the generators was processed
and the excitation system was replaced. After checking and evaluation, the unit capacity is
considered to reach 7 MW.



     The primary electric equipment currently in use was manufactured early and some outdated. The
main connection methods are not reasonable. The secondary controlling equipment only adopts the
conventional one.



     In accordance with the status of the current mechanical equipment, the turbines, generators,
governors and excitations system could operate normally over 10 years. However, we recommend the
replacement of part of electric equipment soon.



     Presently the metal structure is essentially sound and only some daily maintenance is enough
for normal operation.



     (4) In comparison with the hydropower station under construction at the upper reach, Binglang
River Hydropower Station seems too small in terms of installed capacity, a big potential available
for future capacity expansion. Based on the geological and topographical conditions, the
construction of a new station at the right bank is feasible as a scheme of capacity expansion. To
reach the same level of utilizing the hydropower potential like the station at the upper reach, the
reasonable installed capacity of Binglang River Hydropower Station



43









 




should be around 45 MW, with annual power generation 220 million kWh. If we consider the role
of storage regulation of the three stations at the upper reach, then we may have an annual power
generation 250.6 million kWh. So it is recommended that the installed capacity of the new station
at the right bank be 24 MW and the total static engineering cost would be 78 million Yuan, as
primarily estimated.




     (5) The purchasing price of Binglang River Hydropower Station is 175 million Yuan. However, if
a new station is to be built at the right bank, the new selling price to the grid could be high and
benefit is higher. The financial indexes are very good. In actual operation, as the new stations
have higher efficiency with higher selling price. Put the new station in priority to generate
electricity, then the financial indexes will be even better.



     (6) The selling price to the grid in the area where Binglang River Hydropower Station is
located in Yunnan province is the lowest in the whole South Grid in China. That is because the
development of local economy is low and is not yet quite open, forming the situation that
electricity of low price is not transmitted out. It could be predicted that with the deepening of
the State’s developing the west process, the local economy there will boom, the channel of
“Electricity transmission from west to east” will further open.



     Constrained by its low level of local economy and west-east electricity transmission not fully
developed, the selling price to the grid in the area where Binglang River Hydropower Station is
located in Yunnan province is the lowest in the whole South Grid in China. With the deepening of
electric power reform and implementation of <Renewable Energy Law> in China, there will be
large room of increase in electricity price to the grid. So, looking forward to the future, the
benefit of Binglang River Hydropower Station will be greater.



     In summary, the project of Binglang River Hydropower Station is satisfactory and the second
phase capacity expansion could enjoy a high rate of return for investment. The overall economic
figures are sound, with bright prospect. The project is evaluated as feasible.

	(III)	 	Operational assets conditions and feasibility of second-phase construction





1. Operational assets conditions




Binglang River Power Station, a run-of-water plant located in Xincheng Town,
Yinjiang County, Dehong, Yunnan Province, was commenced in April 1985 and
completed in June 1988. From 2005 to 2006, the power station was rebuilt
technically. Currently, its total installed capability is 21,000kW, and its average
power generation is 138.15 million kWh.



The total layout of Binglang River Power Station is rational and its design is also
reasonable. Except the water inlet and the open water channel that have a bit

	 	Asset Appraisal Report






defects, the rest structures are designed and built rationally. In the aspects of intensity and
stability, all the buildings are wonderful and the infrastructure is good. In addition,
the construction quality is also wonderful. Even though having experienced for over 19 years, the
whole facilities show good conditions and satisfy all the designed functions. Without any obvious
defect, crazing and leakage, the facilities can be regularly operated within their designed use
life upon finishing some routine necessary maintenance.



According to the specific conditions that the power station was built, the main electromechanical
equipments and electric design are rational. The current electromechanical equipments are
basically those ones purchased in 1986 but parts of them have been technically rebuilt already. In
1999, the speed regulator was rebuilt into PC speed regulator (with PLC); from 2005 to 2006, the
water turbine replaced its water wheel, the power generator was insulated in site and the field
excitation system was replaced. So far, the output per single machine is 7000kW.



The major existing electromechanical equipments are early ones and some of them are not marketable
already. The existing cabling system is not rational, either. Its secondary control system now
still adopts regular control mode, only DC system was rebuilt.



According to the existing electromechanical equipment conditions, water turbine, power generator,
speed regulator and field excitation system can be operated normally for at least ten years.
However, these equipments feature lagged technologies, low security and huge wastage.



The steel structure is still in good conditions and as long as being repaired and maintained well,
it can be used normally.



2. Feasibility of second-phase construction




Binglang River is the upstream of Daying River, a first-level branch of Ayeyarwady River. Its
total length is 120.2km, and its drainage area is

2310.69km2, showing a feather-like distribution. Within its territory, the average elevation is
1831m. In the water source, the elevation is about 2000m; while in the join of Nandi River, the
elevation is 837m, presenting a natural gap of about 1200m. Its average elevation difference ratio
is larger than 10%, so it’s one of hydroelectric resource-rich medium rivers in Yunnan Province.
Along the river, both banks are covered with thick subtropical broadleaf frees and shrubs. The
forest coverage rate is up to 90%, so there are few soils and sands in the river. Within its
territory, the water quality is very limpid.



For Binglang River, its surface flow is sourced from waterfall mainly and smelting snow
additionally. Thanks to its subtropical wet monsoon climate, its drainage area is full of water
stream in summer.



According to Binglang River Hydroelectric Planning Report (Danzha to Songshan Outfall) formulated
by Baoshan City, Binglang River Hydroelectric Planning Report (Dehong Section) formulated by
Dehong City as well as recent

planning adjustment, two reservoirs and nine power stations are planned to be built along the
trunk stream of Binglang River and the total installed capacity will be up to 666,900kW. In this
planning, two reservoirs and four power stations belong to the upstream city, Baoshan, and the
rest belong to Dehong.



From Binglang River Power Station to the water source, the drainage area is 2160km2 and this area
features the aforesaid contents. In this area, the geographic structure is complicated and crustal
movement is active here. Accordingly, most of its circumferences are earthquake areas and the
basic seismic intensity is 8 degree.



For a long term, due to historical and systematic reasons, the wholesales price of little
hydroelectric power stations are relatively throughout the country and in most of the provinces,
the wholesales price of little hydroelectric power stations are lower than the average wholesales
price. In addition, due to unbalanced economic development, the wholesales power price also
features huge differences locally. It’s forecasted that the wholesales power price still features
huge growth space in company with the West Development Program, local economic development,
consummate west-to-east power transmission channel, deepening of power system reform as well as
implementation of Renewable Energy Act.



In the upstream area of Binglang River Power Station, two reservoirs and seven power stations are
under planning. Upon the completion of three reservoirs in the upstream of Binglang River, the
floodwater storage will be increased hugely and the equivalent storage capability is equal to a
storage-factor-8% reservoir. According to the existing installed capacity, the annual average
power generation will increase about 20 million kWh. If its channel water flow can be matched with
the controlled drainage flow upstream, Binglang River Power Station can increase more than 31
million kWh per annum on average.



Comparing with the hydroelectric resource utility degree in the upstream constructing power
stations, Binglang River Power Station has obviously smaller installed capacity and feature high
potential to increase installed capacity. According to the topographical and geological
conditions, it’s feasible to build a new facility in the right bank so as to increase the power
generation capacity.



The newly-built facilities including water inlet, scouring sluice, water tunnel, pressure
adjustment well, pressurized pipeline, workshops and booster system will be laid along the right
bank. The highest water level is 884.16m at the reservoir, and the lowest water level is 841.00m
at the downstream.



For the second-phase capacity increase, 2*10,000kW installed capacity is recommended to install
and the company needs RMB 68 million for static investment. Taking 3 completed reservoirs upstream
into consideration, 112 million kWh per annum will be increased on average.



Its second-phase capacity increase proposal was ratified by Dehong Development and Reform
Committee in January, 2006. (See DEFAGAITIGAI[2006] No.75 Document).

X. Appraisal Approach




The income approach is adopted in this appraisal assuming the continuous operation of the
enterprise.



(I) Preconditions for Application of the Income Approach




The income approach refers to such an assets appraisal approach that the value of the appraised
assets is decided by means of estimating the expected return of the appraised assets and
converting them into present value. Preconditions for application of the income approach as
follows:




	 	1.	 	The clear property right of the enterprise assets appraised;
	 
	 	2.	 	The future income of enterprises able to be monetarily quantified;
	 
	 	3.	 	The future operating risk of the enterprise able to be monetarily quantified.





(II) Profit Forecast Basis





	1.	 	The basis of this appraisal is established on the precondition of the normal operation of the
enterprise and all earnings are from the normal operation of the enterprise, taking no account of
accidental factors and non-comparable factors.
	 
	2.	 	The profit forecast takes the actual stock assets of the enterprise and has taken the influence
on the normal earnings of the enterprise from the reasonable improvement of stock assets and the
additional investment into

	 	 	consideration.
	 
	3.	 	The profit forecast is established on the findings of audit from Yunnan Huabang, in
accordance with the profit forecast submitted by the enterprise and according to relevant
information collection from inquiry carried out by appraisers. It has necessarily analyzed,
estimated and confirmed the reasonableness of the profit forecast by the enterprise and some
adjustments have been made.






	 	1.	 	Operation materials of the past years provided by Yunnan Huabang;
	 
	 	2.	 	The unification of accounting process adopted.





(III) Appraisal Model of the Income Approach




The appraisal model of the income approach has adopted the pre-interest cash flow after taxes (
CFAT) model.



Pre-interest cash flow after taxes = shareholders’ equity cash flow + interest-payment debt
interests * (1- rate of income tax)



In which:



Shareholders’
equity cash flow = after-tax profit - net investment





			
	Net investment 	  =	  capital expenditure + increase of operation
funds - depreciation and
amortization





(IV) Establishment of the Forecast Period




According to our investigations and analyses, the enterprise will undertake the second-phase
construction of the power station, so in order to reflect its influence on the enterprise cash
flow in the long term, we decided to make ten years as the forecast period, i.e. from 2007 to
2016.



(V) Establishment of Benefit Period




The operation period of the Yunnan Huabang is twenty years as stated in the company regulations,
counting from the issuance of the operation license. The operation period stated in the business
license of the enterprise as a legal person is from January 13, 2004 to January 13, 2024. On the
base of the economic development prospect of generating power by water conservancy, the appraisal
benefit period is permanent, namely from December 31, 2006 to the permanency.



(VI) Establishment of the Discounting Rate




According to the principle of unifying the earning capacity and the discounting rate, the earning
capacity is pre-interest cash flow after taxes, so the discounting rate r will choose the weighted
average cost of capital (WACC), i.e., the return on investment capital, also called investment
capital cost, a comprehensive return rate decided by the structure and return rate of the
shareholders’ equity capitals and interest-payment debenture capitals.



The computing formula is:

	Yunnan Huabang Power Development Co., Ltd.
	 	Share Transfer Project
	 	Asset Appraisal Report






WACC = Ke*We+Kd*(1-T)*Wd

Ke: Shareholders’ equity capital cost;

Kd: debenture capital cost;

We: the ratio of shareholders’ equity capital in the capital structure;

Wd: the ratio of debenture capital in the capital structure;

T: valid income tax rate of the company;





	 	1.	 	Definition of Ke





According to the capital asset pricing model (CAPM) and on this base, considering the individual
risk earning of Yunnan Huabang, the computing formula is:


Ke= Rf+ß×Rpm+A



Rf: risk-free return rate;



RPm: market risk premium;



A: individual risk adjustment.





	 	(1)	 	Risk-free Return Rate Rf
	 
	 	 	 	The annual interest of the proof national debt (five-year term) face value in
2007 (the first term) is 3.81% and if converted into the compound interest,
the interest is 3.55%, so the risk-free return rate is 3.55%.
	 
	 	(2)	 	Enterprise Risk Factor ß
	 
	 	 	 	It will be decided by the mean parameter of Shanghai and Shenzhen
A-Stock Market of the listed companies that are similar to the appraised
enterprise in the recent 100 weeks according to the information from Wind and
after calculation, it is 0.8385.
	 
	 	(3)	 	Market Risk Premium Rpm
	 
	 	 	 	Domestic securities market is an emerging but bundle one. On one hand, the
domestic market has a relatively shorter history data and in the first
several years of its establishment, the speculation atmosphere was pregnant,
so the market fluctuation is large; on the other hand, presently, the control
over the exchange flow under the capital account is strict, plus the
particularity of the stock equity separation, so the stock equity risk
premium deduced directly from the history data has a low reliability, while
in the mature market, owing the long history data, the overall stock equity
risk premium on the market could be got from analyzing the history data, so
the risk premium of international emerging markets commonly could be decided
by the risk premium of the mature market. In this appraisal, the market risk
premium Rpm is 7.5%.

	 	(4)	 	Risk Adjustment Factor
	 
	 	 	 	The existing installed generation capacity of the enterprise has reached
21,000 kW after the rebuilding. After the establishment of the new station,
the installed generation capacity will reach 41,000 kW, but the scale is
still relatively smaller. The commencement of the new station hasn’t yet been
carried out, so there will be some uncertainties involved and the operation
risk is on the high side. The liabilities rate of assets of the enterprise is
relatively high, together with the financing risk from power station
construction, the enterprise financial risk is also on the high side. In the
light of the said reasons, the individual risk regulation A is 2%.
	 
	 	(5)	 	Equity Capital Return Rate r




Ke = Rf+ß×Rpm+A



=3.55%+0.8385×7.5%+2%

   =11.84%





	 	2.	 	Kd is the enterprise’s current contract interest rate, 7.128%.
	 
	 	3.	 	Definition of We and Wd
	 
	 	 	 	Up to the appraisal benchmark day, the interest-payment liabilities of the
enterprise had reached RMB 108 million and the shareholders’ equity RMB
51.2442 million, so:




We=5,124.42/(10,800+5,124.42)*100%= 32%

Wd=10,800/(10,800+5,124.42)*100%= 68%





	 	4.	 	Estimation of the Discounting Rate r
	 
	 	 	 	It shall be estimated according to the valid income tax rate in the
corresponding year and the aforesaid indices.





(VII) Computing Formula




The entire shareholders’ equity is decided according to the present actual operation status of the
appraised enterprise, by means of subsection forecast of the future income of Yunnan Huabang and
converting the income into cash, which then shall be deducted by the interest-payment liabilities.
Firstly, the pre-interest cash flow after taxes of the Yunnan Huabang from 2007 to 2016 is
forecast; secondly, it is presumed that the enterprise will run permanently and the pre-interest
cash flow after taxes remains the same as that of 2006 after the year 2017; thirdly, according to
the selected discounting rate, the aforesaid two-stage pre-interest cash flows after taxes are
converted into cash; finally, they shall be summed up and the entire value of Yunnan Huabang is
figured out. The computing formula is:


In
which:

P:     the entire value of the enterprise;

Rt:    the pre-interest cash flow after taxes in the Tth year;

R:     weighted average cost of capital;

T: the forecast year;

N and (n+1) are the last year of the forecast period and the first year after

     Rn+ 1 : the
pre-interest cash flow after taxes of the (n+1)th year, namely the first-year
pre-interest cash flow after taxes after the forecast period.




(VIII) Selection of Data Estimations




The financial data forecast of Yunnan Huabang has been adjusted based on the operating performance
from the year 2004 to the year 2006, in accordance with national current related laws, codes and
macro-policies, the status and foreground of the China power industry, and trend of Yunnan power

the forecast.




	 	1.	 	Prime Operating Revenue
	 
	 	 	 	The prime operating revenue Yunnan Huabang, as a hydroelectric enterprise, is the income
from power sales.
	 
	 	 	 	In the forecast, the influence on the income from business indicators and the power
generation capacity of the second-phase power station established from the additional
investment have been taken into consideration.






	 	(1)	 	Installed generation capacity: for the old power station, it shall be decided
according to the rebuilt installed generation capacity while for the new one, it shall
be decided according to the designed capacity.
	 
	 	(2)	 	Utilization hours in a year: for both the old and new power station, it shall be
decided according to the designed capacity.

There are 15 workers working for the new power station and wages shall be decided
according to the average wage level of the corresponding year.
	 
	 	(2)	 	The employee welfare cost shall be estimated according to current standards.
	 
	 	(3)	 	Maintenance expenses: in the year 2005 and 2006, the renewal of major

	 	(2)	 	Increase of Operation Funds
	 
	 	 	 	The demand for the operation funds in the company is slim and the cash flow
brought by the daily power sales is able to support the daily
operation turnover, so the increase of operation funds is taken no account of.
	 
	 	(3)	 	Depreciation and Amortization
	 
	 	 	 	The forecast value of the depreciation and amortization is decided on the basis of
forecast depreciation of fixed assets of the general and administrative expenses.

	1.2	 	Corporate History of the Company since January 2004






	 	1)	 	Establishment of the Company
	 
	 	 	 	In January 2004, Zhejiang Development Investment Group Co., Ltd and Zhejiang Huabang
Electric Power Development Co., Ltd applied to Yingjiang County Administration for
Industry and Commerce ( the “Local SAIC”) for the establishment of the Company. The
registered capital of the Company was RMB40,000,000. Yingjiang Zhongyuan Public
Accountants Co., Ltd issued the capital verification report (Ying Zhong Kuai Yan Zi (2004)
No. 5) dated 12 January 2004, certifying that as of 12 January 2004, the Company has
received the paid-up registered capital RMB40,000,000 contributed in cash by shareholders,
whereby Zhejiang Development Investment Group Co., Ltd held 60% shareholding of the
Company and Zhejiang Huabang held 40% shareholding of the Company.
	 
	 	2)	 	The first share transfer in 2004
	 
	 	 	 	On 26 May 2004, the Shareholders’ Meeting of the Company made a resolution approving the
share transfer from Zhejiang Development Investment Group Co., Ltd to Zhejiang Huabang and
Zhejiang Dahua, according to which Zhejiang Development Investment Group Co., Ltd
transferred 11% equity stake of the Company to Zhejiang Huabang and 49% to Zhejiang Dahua
respectively. On 3 June 2004, Zhejiang Huabang signed the share transfer agreement3 with
Zhejiang Development Investment Group Co., Ltd, by which 11% of the equity stake of the
Company held by Zhejiang Development Investment Group Co., Ltd was transferred to Zhejiang
Huabang. The Company applied to the Local SAIC for the alteration registration on 28 June
2004. Thus, Zhejiang Development Investment Group Co., Ltd no longer held any share of the
Company.
	 
	 	3)	 	The change of Legal Representative of the Company
	 
	 	 	 	On 28 June 2004, the Company applied to the Local SAIC for the alteration registration
with respect to the change of legal representative of the Company, from Wu Heng to Zhou
Jian Bin.
	 
	 	4)	 	The change of the Company’s name in 2005
	 
	 	 	 	The Company’s name was changed from “Yingjiang County Huafa Electric Power Development
Co., Ltd” to “Yunnan Huabang Electric Power Development Co., Ltd” in 2005. Yunnan
Administration for Industry and Commerce approved such change of name on 4 August 20044.
Shareholders’ Meeting of the Company made a resolution dated 2 March 2005 giving consent
to the change of the Company’s name. The Company has completed the procedures of
alteration registration with the Local SAIC.
	 
	 	5)	 	The increase of registered capital of the Company in June 2005
	 
	 	 	 	On 2 June 2005, Shareholders’ Meeting of the Company made a resolution on the increase of
registered capital of the Company from RMB40,000,000 to RMB50,000,000 by both two
shareholders on a pro rata basis. Dehong Qiushi Public Accountants Co., Ltd issued the
capital verification report (No: De Qiu Kuai Shi Yan Zi [2005] No 45) dated 14 September
2005, certifying that as of 31 August 2005, the Company has received the newly-increased
registered capital RMB10,000,000 from both two shareholders and the total paid-up
registered capital of the Company is RMB50,000,000. The Company made corresponding

	 	 	 	amendments to the Articles of Association of the Company and completed the procedures of
alteration registration with the Local SAIC.
	 
	 	6)	 	The second share transfer in February 2006
	 
	 	 	 	On 23 February 2006, Zhejiang Huabang entered into the share transfer agreement with Ye
Jian Hua and Zhou Jian Bin, by which Ye Jian Hua obtained 30% of the equity stake of the
Company and Zhou Jian Bin obtained 21% of the equity stake of the Company. Zhejiang
Huabang exited completely from the Company. The Shareholders’ Meeting of the Company made
a resolution on 23 February 2006 approving such share transfer and made corresponding
amendments to the Articles of Association of the Company. The Company has completed the
procedures of alteration registration with the Local SAIC.

	 	•	 	written reply concerning the approval of Binlangjiang Power Station planning task
issued by Planning Commission of Yunnan Province in 1978. The document number is Yun Ji She
(78) No 5415;
	 
	 	•	 	Planning Commission of Yunnan Province approved the preliminary design report of
Binlangjiang Hydroelectric Power Station on 14 September 1984. The approval document

	 	•	 	Development and Reform Commission of Dehong Autonomous Prefecture approved the
second phase of technical reform and capacity increase for Binlangjiang Hydroelectric
Power Station on 7 January 2006. The approval document is De Fa Gai Ti Gai [2006] No
75.






	 	(vii)	 	Official document confirming the owner of Binglangjiang Hydroelectric Power Station






On 13 May 2004, the People’s Government of Dehong Autonomous Prefecture issued a
written reply (document number: De Zheng Fu [2004] No 79) concerning the
confirmation of the owner of Binglangjiang Hydroelectric Power Station. In
accordance with this written reply, the owner of Binglangjiang Power Station is
Yingjiang County Huafa Electric Power Development Co., Ltd6.





	 	Note: 	 	 Binlangjiang Hydroelectric Power Station has not been granted Power Generation Permit
Certificate, which is a compulsory requirement for the Company to engage in power generation
business in the PRC. We are informed that the Company has been in process of applying such
Certificate for Binlangjiang Hydroelectric Power Station.






	 	(viii)	 	Unavailable Approvals






	 	i)	 	documents concerning approving the construction of Binlangjiang Hydroelectric

	 	Note:  	 	The construction of Binlangjiang Hydroelectric Power Station project was completed in
1988. Many prevailing PRC regulations were not promulgated then, therefore, compared with
the newly-developed projects, a number of governmental approvals for Binlangjiang project are
unavailable. Moreover, we are informed that part of the reason is that some of the said
approvals were missed in the course of handing-over from the original owner to the Company.
However, considering the People’s Government of Dehong Autonomous Prefecture has confirmed
the ownership of the Company on Binlangjiang Hydroelectric Power Station by issuing De Zheng
Fu [2004] No 79 document, we understand it is unlikely for the local governmental authorities
to impose any administrative penalties on the

Company for the lack of governmental approvals due to the historical reasons. In
addition, we have received from the Company an Ask for Instructions dated 6 March
2007, which was submitted by the Company to People’s Government of Dehong Autonomous
Prefecture recently. By stamping on such Ask for Instructions, People’s Government
of Dehong Autonomous Prefecture confirmed that: (1) the Company is the legal owner of
Binglangjiang Hydroelectric Power Station; and (2) Binglangjiang Hydroelectric Power
Station is being legally and normally operated. We understand, to certain extent,
such Ask for Instructions may be deemed as a further assurance.

for the use of such lands. After the proposed equity stake transfer, the Company will be
converted from a domestic enterprise into a foreign-invested enterprise, there may be a
possibility that the Company would be required by the local governmental authority in charge
of land administration to pay so-called using-site fee. In order to determine this issue, we
have consulted with local governmental authority but failed to secure a clear answer.
According to our experience, with regard to the using-site fee, to certain extent, the local
government may have its own discretion. In addition, no assurance can be given that such
preferential treatment of allocating land use right would not be changed by local
governmental authority.

Oversight Board (United States). A review of financial statements consists principally of
applying analytical procedures and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted, the objective of
which is the expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.



Based on our review, we are not aware of any material modifications that should be made to the
accompanying financial statements for them to be in conformity with U.S. generally accepted
accounting principles.

1. Principal activities and organization.





YUNAN HUABANG Electric Power Development Co., Ltd was incorporated under the law of
the People’s Republic of China in January 2004 as Yingjiang County Huafa Electric
Power Development Co., Ltd. The Company’s name was changed to Yunnan Huabang Electric
Power Development Co., Ltd from Yingjiang County Huafa Electric Power Development Co.,
Ltd in 2005. The establishment of the Company co-occurs with the acquisition of 100%
stake of Binglangjiang Hydroelectric Power Station project, which was valued at RMB
171,000,000. The Company is principally engaging in the operation, management and
investment of the hydroelectric project.




The Company was established with registered capital of RMB40,000,000, 60% of which was
contributed by Zhejiang Development Investment Group Co., Ltd and 40% of which was
contributed by Zhejiang Huabang.




In June 2004, Zhejiang Development Investment Group Co., Ltd transferred 11% of the
equity stake of the Company to Zhejiang Huabang and 49% of the equity stake of the
Company to Zhejiang Dahua respectively. Zhejiang Development Investment Group Co.,
exited completely from the Company.




On 2 June 2005, shareholders’ Meeting of the Company made a resolution on the increase
of registered capital of the Company from RMB40,000,000 to RMB50,000,000 by both two
shareholders on a pro rata basis.

On 23 February 2006, Zhejiang Huabang entered into the share transfer agreement with
Mr. Ye Jian Hua and Mr. Zhou Jian Bin, by which Mr. Ye Jian Hua obtained 30% of the
equity stake of the Company and Mr. Zhou Jian Bin obtained 21% of the equity stake of
the Company. Zhejiang Huabang exited completely from the Company.



2. Bank Loans





The Company borrowed RMB 120,000,000 from Agricultural Bank of China, Dehong Branch in
April 2004, with annual interest rate of 6.138% for a term of five years. As of December 31,
2006, the Company had paid off RMB
12,000,000, with RMB 108,000,000 principal outstanding.




The borrowing from Agricultural Bank of China, Dehong Branch was used for part of
the RMB 171,000,000 payment for acquiring Binglangjiang Hydroelectric Power Station.

	 	(A)	 	Economic and Political Risks
	 
	 	 	 	The Company’s operations are conducted in the PRC. Accordingly, the Company’s

significant risks not typically associated with companies in North America and
Western Europe. These include risks associated with, among others, the
political, economic and legal environment and foreign currency exchange. The
Company’s results may be adversely affected by changes in the political and
social conditions in the PRC, and by changes in governmental policies with
respect to laws and regulations, anti-inflationary measures, currency
conversion, remittances abroad, and rates and methods of taxation, among other
things

Company enjoys a “two years’ exemption, three years’ half reduction” policy,
which means the Company is exempt from corporate income tax for its first two
years and is then entitled to a 50% tax reduction for the succeeding three
years. The Company successfully secured one more year’s exemption. So there is
no income tax in 2006, which is its third year of operation. The Company’s
first profitable tax year is 2007 and it is subject to a reduced tax rate of
7.5%.

1.3 Brief of Evaluation




1.3.1 Description of the river basin and hydropower cascades planning




     Donghe
River is the
1st step
tributary of Jialing River at the left bank, originating from southern foot of Micang of Qinlin
Mountain, flowing Shaanxi and Sichuan provinces from north to south., flowing into Jinling River in
Sichuan province. Donghe basin belongs to subtropical humid monsoon climate zone, located at the
edge of the Sichuan Basin. It has the features of mild climate and plentiful rainfall. The total
length of Donghe River is 293 km, natural drop 536 m, catchment 5040km2, mean annual
flow in the whole catchment 109.1m3/s, the theoretical hydropower potential 237000 kW,
being the medium size river rich in hydropower potential in Sichuan province.



     In its mid and lower reach, Donghe River flows by Cangxi county, with its total length
110.4 km, concentrated drop 78 m. According to <Planning report of hydro energy for
Cangxi section of Donghe River> compiled in Dec 2005, 6 cascade development, i.e.
Dongxi, Fengziyan, Likou, Yangmoshi, Beituo and LiYuan hydropower stations, were adopted,
with the total installed capacity 50300 kW, annual power generation 20300 kWh, with the
total investment 488.85 million Yuan.



1.3.2 Status of LiYuan Station




     LiYuan Hydropower Station is the last of the 6 cascade stations of Donghe in Cangxi
county. The station was started to be built in Nov 2004 and put into operation in Aug
2006. The installed capacity of LiYuan Hydropower Station is 12000 kW, mean annual power
generation 44.15 million kWh. Its annual utilization hour is 3679 h.



     LiYuan Hydropower Station is of river-bed type. Its engineering pivot from the left
to the right is the step-up substation, power house, sluice gate, floating gate, ship
lock, spill weir at the right bank and etc. The step-up substation, power house lies at
the left bank and the power house is part of the water retaining structure. The main power
house consists of main machine section and installation section. In the main machine
section are
equipped with 6 axial propeller type turbine-generators. The auxiliary house lies at
lower reach of the main power house and left end. The spillway gate is located at the
river-bed, 180 m off. At the fixed weir is equipped with 18 hydraulic automatic floating
gates (5 m height × 10 m width).



     LiYuan Hydropower Station is equipped with 6 axial propeller type turbine-generators,

2









 







head 10.3 m, unit flow
24m3/s,
rpm 214.3r/min and the rated output 2128 kW.


The type of the
identical generator is SF2000-28/2840, rated capacity 2000 kW, rated voltage 6.3 kV. The electric
controlling part adopts computer supervision, aided by the conventional controlling mode.



1.3.3 Engineering evaluation of LiYuan Hydropower Station




     (1) Scale of installed capacity and amount of power generation




     After evaluation and checking, the installed capacity 12000 kW is reasonable in the
recent period and the mean annual generation 44.15 kWh is reliable.



     (2) Main structures




     After checking the geological and topographical conditions, the dam axis selected is
reasonable and the layout of the pivot structures reasonable too.



     The spillway gate is the hydraulically automatic floating gate mounted on the fixed
weir. The selection of such gate is reasonable. The foundation at the spillway gate is
sandstone. Generally speaking, the geological condition is good. After excavation and
curtain and consolidation grouting at the dam foundation, it can generally meet the demand
of constructing the dam. The fixed weir is of embedded rock concrete structure, with good
construction quality. In appearance, there are no defects, cracks or leakage, especially at
the foundation part. The energy dissipation mode is bottom flow and surface flow, equipped
with concrete dissipation pond which is also feasible. The hydraulic automatic floating
gate can work normally and its quality can meet the demand of construction.



     The foundation of the power house is complete new rock, able to meet the engineering
demand. Its structure could meet the demand of intensity and stability. Both the power
house and house area can meet the demand of flood protection. The layout of power house is
not quite reasonable, causing inconvenience in operation and maintenance. There is the
slight leakage in part of the power house. The decoration of construction is simple, but
it can meet the engineering demand.



     (3) Electric mechanical equipment and metal structures




     The selection of the main electric-mechanical equipment is reasonable, able to meet
the operation demand in function. The units operate stably, noise normal, output rate
reached.



     The connection mode is reasonable. The secondary controlling equipment can basically
meet the protection
demand of the station. But the metering functions of the computer supervision system
seem too simple.



     The layout of the water, oil and gas pipes for the units can meet the demand of use.
But it is not convenient for future maintenance. There is no stop gate for the intake,
unsafe.

1.3.4 Status of Fengziyan Hydropower Station




     Fengziyan Hydropower Station is the 2nd of the 6 cascade stations planned. The station
started its construction in Dec 2005 and it is now under construction. It will be put into
operation in Sept 2007. The installed capacity of Fengziyan Hydropower Station is 12000 kW,
mean annual power generation 46.92 million kWh. Its annual utilization hour is 3819 h.



     The Station is of river-bed type. Its engineering pivot from the left to the right is
the non-spillway dam section at the left bank, ship lock(scouring gate), power house,
step-up substation, non-spillway dam section at the right bank, and the total length of
the pivot is 180.28m. The floating gate dam section is located at the river-bed , of which
120 m ahead is the spillway front, on the crest of it are 12 hydraulic automation floating
gates 7m( height )×10m( width ), ship lock, spill weir at the right bank and etc. The
step-up substation, power house lies at the left bank and the power house is part of the
water retaining structure. The auxiliary house lies at lower reach of the main power house
and left end. The spillway gate is located at the river-bed. The ship lock(scouring gate)
is between spillway gate and the power house. Both the power house and substation lie at
the right bank and the power house is part of the water retaining structure. The main
power house consists of main machine section and installation section. In the main machine
section are equipped with 4 axial propeller type turbine-generators. The auxiliary house
lies at the right side of the main power house.



     Fengziyan Hydropower Station is equipped with 4 axial propeller type
turbine-generators, typed ZDJP502-LH-225, its runner diameter 2.25 m, rated head 13.2 m,
unit flow 30 m3/s, rpm 214.3 r/min and the rated output 3405 kW. The type of the
identical generator is SF3200-28/3250, rated capacity 3000 kW, rated voltage 6.3 kV. The
electric controlling part adopts computer supervision, aided by the conventional controlling
mode.



1.3.5 Engineering evaluation for Fengziyan Hydropower Station




     (1) Scale of installed capacity and amount of power generation




     After evaluation and checking, the installed capacity 12000kW of Fengziyan Hydropower
Station is reasonable, with mean annual power generation 46.92 million kWh reliable.



     (2) Main civil structures




     As the engineering is under construction, it is not possible to evaluate the quality
of the structures to be constructed and operation condition after storing water.



     Based on the topographical and geological conditions at the dam site of Fengziyan
Hydropower Station, the position of the dam axis is rational and the general layout of the
pivot structures reasonable.




4











 





     The spillway gate is the hydraulically automatic floating gate mounted on the fixed
weir. The selection of such gate is reasonable. The foundation at the spillway gate is
sandstone. After excavation and curtain and consolidation grouting at the dam foundation,
it can generally meet the demand of constructing the dam. The fixed weir is of embedded
rock concrete structure. The structure size designed to meet the need of the hydraulic
automatic floating gate and flood discharging can completely meet the demand of standard to
intensity and stability. The energy dissipation mode is bottom flow one, equipped with
concrete dissipation pond which is also feasible. The adoption of the floating gate with
the height of 7 m for Fengziyan Hydropower Station has certain risk.



     The foundation of the power house is complete new rock, and treatment of consolidation
and curtain grouting has been made, able to meet the engineering demand. The layout of
power house is reasonable.



     (3) Electric mechanical equipment and metal structures



     It is reasonable for the selection of the main electric mechanical equipment for
Fengziyan Hydropower Station, able to meet the demand for operation. Its layout is also
reasonable, as well as the main connection mode and secondary design. As Fengziyan
Hydropower Station is not yet commissioned and most equipment is not yet installed, so no
evaluation is made on the operation condition of the equipment.



     There is no stop gate, unsafe.



1.3.6 Development prospect




     (1) Electric power development planning



     The electric power source in Sichuan province is mainly hydropower. By the end of
2005, the total installed capacity was 22.9588 million kW, of which the thermal power,
representing 34.8%, the hydropower, representing 65.11%. The total power generation was
101.7 billion kWh, increased by 14.86% as compared with that in previous year. Together
with the rapid power source development, the grid development was also strengthened. The
main 110kV, 220 kV, 500 kV diagram system has primarily been formed in Sichuan power grid



     In the whole province according to forecast; by 2010 the maximum power generation load
21.81 kW and maximum power demand 124.1 billion kWh; by 2015 the maximum power generation
load 29.32 kW and maximum power demand 166 billion kWh.



     Sichuan is rich in energy resources, especially the hydropower resource. It is an
important step in the whole implementation strategy of the west area development campaign to
make use of electricity transmission from west to east and develop the rich clean hydropower
potential in the province so as to realize its electricity transmitted out. According to some
documents issued by the province, the planning for the transmission of electricity from west
to east is:



5









 







By 2010, the installed capacity of transmission out 8 million kW and the amount
of energy 38 billion kWh; By 2015, the installed capacity of transmission out 12 million kW
and the amount of energy 57 billion kWh; By 2020, the installed capacity of transmission out
16 million kW and the amount of energy 76 billion kWh.



     By now, most of the energy and power in Cangxi has been supplied by Sichuan grids.
According to the electrification planning of Cangxi county, the maximum load will reach
42000 kW with annual electric power 184 million kWh by 2008. By 2010, the maximum load will
reach 50000 kW with annual electric power 210 million kWh. By 2015, the maximum load will
reach 70000 kW with annual electric power 280 million kWh.



     The development of Donghe cascade
 hydropower stations has been included in the “11th
-Five-Year Plan” of GuangYuan city. Also, the 220 kV substation in Cangxi county has been
planned to construct.



     (2) Development
 of Donghe cascade hydropower stations and market demand



     By primary balance of
 power and energy, after operation of LiYuan and Fengziyan
Hydropower Stations, the load demand in Cangxi power grid will still not be met by 2008.
After operation of the other 4 cascade stations at Donghe river by 2010, there will be
surplus energy in rainy season to be transmitted to the Sichuan grid and to be adsorbed in
the nearby counties. After 2015, there will be shortage of energy and power in Cangxi grid,
in need of supplement by large grids. So, the product of Donghe cascade hydropower stations
will find big market in either short term or long term.



     (3) Adjustment
 of selling price to the grid



     Currently, the selling
 price of Donghe cascade SHP stations is 0.29 Yuan kWh. The
price is actually higher than other places in Cangxi conty, and higher even in GuangYuan
city. It could be predicted that the increasing space is not much, even if there is
adjustment in the near future.



     (4) Forecast
 for Upper cascade development in the long term



     In accordance with
 <General planning report of hydropower development in Sichuan
province>, at the upper reach of Donghe River in Wangcang county, the Guanziba reservoir
has been planned. The main function of Guanziba reservoir (grade II) is for irrigation in
combination with generation and flood prevention. The normal 3 storage level is 573 m, max
dam 3 height 116 m, total storage 565 million m 3,
 valid storage 385 million
 m m3.
The planned irrigation area is 2.124 million mu, the gross water supply from the
reservoir 729 million m . According to primary analysis, its construction will have
influence in 25 years on the cascade stations planned and the utilizable water at the
cascade stations will be reduced. As each of the cascade stations has already paid back the
loan after 25 years and gained benefit. Hence, the construction of Guanziba reservoir has
little impact to the cascade SHP stations below in fact.

1.3.7 Economic evaluation




     The purchase of LiYuan and Fengziyan Hydropower Stations is 154 million Yuan, total
installed capacity 24000 kW and mean annual power output 91.07 million kWh.



     According to the present off-take price 0.29 Yuan/kWh, the static investment payback
period is 7.86 years.



1.3.8 Evaluation conclusion




     (1) The installed capacity of LiYuan Hydropower Station is 12000 kW, designed mean
annual output 44.15 million kWh. The installed capacity of Fengziyan Hydropower Station is
12000 kW, designed mean annual output
46.92 million kWh. After evaluation, the installed capacity of the two stations is reasonable,
mean annual output reliable.



     (2) The selection of LiYuan Hydropower Station site is correct, general pivot layout
reasonable. The design of the pivot structures can meet the demand of intensity and
stability. But there is defect for construction quality of the power house, with some
leakage, but not much effect on operation. The construction quality of other structures is
OK. The pivot structure can meet demand of operation.



     The selection of the main electro-mechanical equipment is reasonable and the functions
can meet the demand of operation. Generally, the level of electro-mechanical equipment is
not high. The functions are simple, but can
basically meet the demand of operation.



     (3) The selection of Fengziyan Hydropower Station site is correct, general pivot
layout reasonable. The layout of pivot structure is basically reasonable. Structurally, it
can meet the demand of intensity and stability. From the civil works built, the
construction quality is relatively better. From the design data and site conditions, the
pivot structures can meet the demand of operation.



     The selection of main electro-mechanical equipment is reasonable. The main and
auxiliary equipment ordered can meet the demand of operation, functions able to meet the
demand of power generation. On the whole, the level of the electro-mechanical equipment is
ordinary.



     (4) The purchase price of LiYuan and Fengziyan Hydropower Station is 154 million Yuan,
with the evaluation of the current off-take price, the static investment payback period is
7.86 years. The project is feasible.



     (5) In accordance with the electric power development plan, the product of Donghe
cascade stations will find good market either in the near future or in the long run.
The development at the upstream does not have much impact on this project. Currently,
the off-take price in GuangYuan city is medium and the price will be increased with
the regulation of policy.



     (6) The exploitation condition of the remaining 4 cascades at the Cangxi section is
all ideal, proper scale and good economic indexes. The preliminary design and
necessary procedures have all been finished. If fund is available, the



7









 







construction
may start. After the completion of purchase of LiYuan and Fengziyan Hydropower
Stations, the development of the remaining 4 stations may start, so as to increase
benefit.



     In short, the
 resource of LiYuan and Fengziyan Hydropower Stations is very good. The
design and construction of each pivot structure can meet the demand of intensity and
stability. The development prospect of the other 4 stations is satisfactory. The project is
rated as feasible.



2. General of Basin Planning




2.1 General Description of the Basin



Donghe river, a tributary at the left bank of Jialing
 river on the upper & middle reaches,
originates from the south foot of Micang hill, Qinling mountain ranges, and its upstream is
composed of two water sources, i.e. one is Kuantan river in the east originating from Yaojiaba,
Nanzheng county of Shaanxi province, and the other is Yanjin river in the west originating at
Sanxinyan, east Lipinchang of Ningqiang county in Shaanxi. Two rivers converge at Shuanghechang
and hereafter Donghe river gets its name. Donghe river flows through Shaanxi and Sichuan
provinces from north to south, and pours into Jialing river in Langzhong city, Sichuan. The river
accommodates a relatively larger tributary called Cha river at Yuanbachang, the downstream.
Donghe river extends a full length of 293km, 3 with the total catchment area of 5040
 km2 and
the mean annual flow of 109.1m3 /s.




     Donghe river goes from
 northeast to southwest, with the river basin shaping as a fan.
The river reach above Wangcang county belongs to Daba mountainous area, with steep slopes
and turbulent rapids, and both banks are about 1,500m high. From Wangcang county to
Jiachuan, a valley extends for over 10 km and both banks are in hilly areas, then followed
by low hills from Jiachuan to Dongxi, and the river course becomes narrow. After that reach
are deep canyons till to the estuary, and the river course bends and water flows smoothly.
The valley is sometimes wide or narrow with lots of shoals. There are small terraces along
the river reach, and the mountain at both banks is 200-300m high.



     In the basin, the north is higher than the south, and at the upstream are high
mountains, steep slopes and deep valleys in a long and narrow V-shape. The slope is gentle
at the mountain foot, and both banks have been reclaimed for arable lands. There are dense
forests above Hemengzi of Kuantan river and Wanjia of Yanjin river, so vegetation there is
perfect. Below Mengzi and Wanjia the vegetation is relatively poor, mainly with barren
soil, exposed rock,



8









 







weed and shrub, so water & soil erosion
 seems heavy. The downstream is
inside Sichuan basin, and arable lands are mostly located at each terrace. The vegetation is
well conserved, water & soil erosion is not serious and the riverbed is laid with gravel and
scree.



     Donghe river
 flows through Cangxi county for its middle & lower reaches, with a length
of 110.4km in the county. Cangxi county is located at the middle reach of Jialing river,
upstream of Yangtze river, and it is also at the south foot of Daba mountain and north edge
of Sichuan basin. In the subtropical 2 monsoon humid climate area, the county covers a
total area of 2,331km2 with arable lands
 of 570,000 Chinese mu (38,000 hectares). The total
population is 767,000 inside 39 townships, and it borders Bazhong and Nanjiang in the east,
Langzhong in the south, Jiange in the west, and Wangcang and Yuanba in the north. Inside
the area there are lots of low
hills and valleys, the elevation is generally 380-1,000m, and Jialing river and Donghe
river flow through its hinterland.



     The economy
 in Cangxi county is agriculture-based, and its economic base is relatively
poor owing to hilly region, barren land and dense population. After the reform and open
policy, the local economy is quickly developed and the living standard of people is improved
remarkably. The GDP growth there has been over 10% for successive 13 years, and the industry
structure gets rational. Cangxi county  is rich in natural resources, among which natural
gas reserve is 5 billion m3
 and exploitable hydropower amounts to 1,018MW. At present, the
exploration of natural gas is managed by the government, which begins to benefit the local
people for their living and production. However, the used hydro energy including the just
operated LiYuan hydropower station, is only 2.2% of the total exploitable, so there is a huge
potential for hydro-energy development. In 2004 the government of GuangYuan city, Sichuan
lists LiYuan hydropower station to be a key project for attracting outside investment for its
development, thus unveiling the prelude for development of Donghe river cascade hydropower
stations in Cangxi.



2.2 Hydrology and Weather




     Donghe river basin belongs
 to subtropical monsoon climate area with humid feature. It is
located at the edge of Sichuan basin, alternatively affected by storms from Daba mountain and
Longmen, and there are air vortices. Therefore, there weather is mild and rainfall is
plentiful. Donghe river basin is affected by stormy rain, and the average mean precipitation
amounts to over 1000mm. There is no much change about the rainfall year to year, but the
annual rainfall is unevenly distributed. The basin receives frequent rainstorms during summer
and autumn, rather strong, but quite short, hereby resulting in a sudden & sharp flood rise
and fall. The region from Jiulongshan, upstream of Donghe river to Qiping, belongs to a heavy
rainstorm area in the east, with



9









 







mean annual precipitation of 140mm per 24 hours, and that in
Cangxi and Wangcang is 120mm per 24hours, then gradually decreased to about 100mm per 24hours
in the south. Heavy storms mostly fall in the period from June to September, about over 50% of
the whole year, and a stormy weather usually remains about 3-7 days for its process. Below
Wangcang it belongs o to a warm and dry weather in winter, and the temperature  averages at
above 50 C in January, and average temperature is more
 than 250 C in July. There is no much
temperature change from year to year, but it varies vertically and is much different between
north and south.



     On the main stream of
 Donghe river basin, there is Wangcang  hydrological gauge
station with a control catchment area of 2,701km2 at the
upstream, and  Qingquan hydrological gage station with a control catchment area of
5,011km2 at the downstream. These
 two gauge stations both have recorded a long-term
hydrological data, and can be taken as reference stations to underake hydrological analysis
& calculation for the cascade hydropower stations inside the basin. Water in Donghe river
basin is mainly supplied by rainfall, and it is very plentiful but the year-to-year and
annual changes are both relatively distinctive. According to the statistics of measured3
data at Qingquan gauge station, the maximum annual  mean flow is 246
 m3 /s (1981), the
minimum annual mean flow is 37.2 m3 /s (1979),
 and the rate between the maximum and the
minimum is 6.61. The runoff mainly concentrates in May-September, 79.7% of the total annual
runoff, and water is much rich in June, July and August. The dry period is from October to
the next April, and water is mainly from underground, 20.3% of the total, among which the
period of January-February is the driest, about 2.5% of the total runoff.



     Floods in Donghe
 river attribute to rainstorm, and the flood occurrence echoes the
rainfall period. The flood generally happens during June to September, and concentrates
mostly in July-August, and it usually undergoes for 3~5 days. There is a big year-to-year
change about the maximum flood-peak flow, and the ratio between the measured maximum value
and the minimum value is up to 26.4.



2.3 Planning & Development of Cascade
 Hydropower Stations



Donghe river has a total length of 293km and a
 natural fall of 1,536m. The average gradient  of
river course is 5.2‰, the catchment area above the estuary is 5,040km
2, the mean annual flow is
109.1m3 /s, and the theoretical hydropower
 potential amounts to 237MW, so it is one of
the medium-sized rivers with quite rich hydropower resources in Sichuan province. Restricted by
natural and socioeconomic conditions, hydro-energy development & utilization is still at a very
low stage in Donghe river basin. Donghe station, with an installed capacity of 3MW, has been set
up in Wangcang county, upstream of Donghe river, and Luojiatan hydropower station is built up
downstream in Langzhong


10









 






county, with an installed capacity of 5MW. Donghe river has a length of
110.4km in Cangxi county, with a fall of 78m and an average gradient of 0.71‰. As early in 1987,
Hydropower Bureau of Cangxi County has compiled “Hydropower Planning Report on Donghe River in
Cangxi County”, inside which a developing proposal has been put forward to set up four cascade
stations on the main reach of Donghe river in Cangxi. However, the proposal involves a high dam
and it is very difficult to construct at that time. Furthermore, the main reason is the project
will submerge lots of arable lands and resettle a large population, and it would lead to
social and environmental issues. Therefore, in 2005 Water Resources Bureau of Cangxi County
entrusts Water Resources and Electric Power Investigation, Design & Research Institute of
Nanchong in Sichuan to carry out a planning again for hydro-energy development on this river
reach. As illustrated in the “Planning Report on Hydro-energy Resources of Donghe River in
Dongcang” complied by this institute in December 2005, the gradient of this rive course is small,
and at both banks are situated lots of arable lands, townships and dense population, so it is
unsuitable to set up any big reservoir or diversion-type hydropower station, but instead, a
cascade development with low gate dams can be applied there. After compared among different
proposals, it is determined to set up six cascade stations such as Dongxi hydropower station,
Fengziyan hydropower station, Likou hydropower station, Yangmousi hydropower station, Beituo
hydropower station and LiYuan hydropower station with a total installed capacity of 50.3MW and
total generation of 20.3MWh, and the total investment amounts to RMB488.85 million Yuan. The
dynamic economic index of each cascade station is shown in Table 2-1.




     The development right of all the proposed six cascades is acquired by Jianghe
Hydropower Development Co. Ltd. in Cangxi county, and the development has started. LiYuan
hydropower station starts its construction on November 18, 2004, is commissioned on June 5,
2006 and put into normal operation on August 23, 2006. Since December 2005, Fengziyan
hydropower station is still under construction, and is planned for operation in September
2007. Preliminary designs and project approvals have been finished for other 4 stations,
and the construction can be started when fund is available.



3. Status Quo of Liyuan Hydropower Station



LiYuan hydropower station is the last of 6 cascades proposed on Donghe river, and as a power
station in river channel, it is situated at Renhe village, Zhongtu township of Cangxi county, 42km
away from the downtown of Cangxi county. As a key project of GuangYuan city, Sichuan for
attracting outside investment in


11









 






2004, its construction is started on November 18, 2004, and
commissioned on June 5, 2006 and put into operation on August 23, 2006. The station hasn’t been
officially accepted until now. The CDM (clean development mechanism) project of LiYuan hydropower
station cooperating with ENEL in Italy has been approved by National Development and Reform
Commission in November 2006 (Document No. [2006]2410) and is being registered at the CDM Executive
Board (EB) of UN.




3.1 Hydrological Condition



The catchment area above the dam site
 of LiYuan hydropower station covers an area of
4,934km2,
 only 100km2 less than that of Qingquan hydrological gauge
station where is 10km away at the downstream, so it has the aforesaid hydrological &
meteorological features of the basin completely. According to the data of Qingquan
hydrological station, it is analyzed and calculated that the mean annual precipitation
inside the basin is about 1220mm, the mean annual flow 95.1 m3 /s,
 the annual mean runoff is
2,999 million m3
 and the mean annual runoff depth is 608mm3.
 The peak flow of design flood
with a cycle of 50 years is 12,165m/s, and the peak flow of check flood with a cycle of 500
years is 16,890 m3/s.

in river channel, surrounded by solid hills. The stratum of reservoir area is constituted by
sandstone and clay rock with less water penetration, and no rupture structure is found
extending out of the reservoir. Meanwhile, the storage level is relatively low, and there is
no permanent leakage issue. The slope of reservoir bank is gentle, covered with a very thick
layer, and underlying rock is complete, and furthermore, there is no evident poor structure
that would lead to the instability of reservoir bank. Therefore, there would be no large
landslip and the bank slope is rather stable inside reservoir area.

overlying stratum and followed with sandstone. There is no found a certain scale of
rupture formation or dense joint belt inside dam region. The foundation of powerhouse and
scouring sluice is made of middle or fine sandstone, with a complete, solid and stable
structure. The foundation of overflow gate is quite solid at the left riverbed and the
right bank, which is made of weakly weathered middle & fine sandstone, but relatively poor
at the right riverbed because it is mud siltstone. The ship lift and the right overflow
weir are situated on the hillside of left bank with foundation of weakly weathered middle &
fine sandstone, and the geological condition is fairly good there.

3.6 Reservoir Inundation and Permanent Land Use



According to “Design Criteria on Land Acquisition & Resettlement for Water Resources &
Hydropower Projects” (SL290~2003), and also combining actual situations in the reservoir
area of LiYuan hydropower station, different flood standards are applied for various
inundated objectives, as follows:




     Arable land and garden plot adopts a flood standard with a cycle of 5 years (P=20%);



     Forest adopts the standard of normal storage level;



     Residential area and common facilities adopt a flood standard with a cycle of 10 years
(P=10%);



     LiYuan
 hydropower station is designed to have a normal storage level of 368.00m, a
backWater length of 24.5km on the main reach, and reservoir storage of 30.80 million
 m3.
The reservoir mainly inundates houses, arable lands, garden plots, forests and part of
water resources facilities, itemized as houses of 214.00m2,
 arable lands of 80.00 Chinese
mu (one hectare equals to 15 Chinese mu), wastelands of 113.3 Chinese mu, garden plots of
12.5 mu, forests of 5.5mu, a bridge and a small-sized irrigation & drainage station.



     Based
 on the above-mentioned inundation, a static investment of RMB2,583,000 Yuan is
used to compensate reservoir inundation, among which RMB1,747,000 Yuan is used for
resettlement in rural area, RMB5,000 Yuan for restoring the water resources facilities,
RMB83,000 Yuan for clearing up the reservoir bottom, RMB73,000 Yuan for other expenses and
RMB430,000 Yuan is ready for unforeseen expense.



19









 





     According to the actual station condition, totally 40 Chinese mu of permanent land is
occupied, inside which there are slopes of 13 mu and arable lands of 27 mu. The total
static investment for permanent land occupation amounts to RMB374,700 Yuan, i.e. RMB72,700
Yuan for slopes and RMB302,000 Yuan for arable lands.



3.7 Engineering Characteristics



The engineering characteristics of LiYuan hydropower station are shown as Table 4-1.




4. Status Quo of Fengziyan Hydropower Station



Fengziyan hydropower station, a project in river channel, is the second cascade among these 6
stations planned on Cangxi section of Donghe river, which is located at Fengziyan, upstream of
Tuli township, Cangxi county, and it is 85km away from the downtown of the county. The
construction of Fengziyan hydropower station is started from December 2005 and it is still under
construction, and to be put into operation in September 2007. The CDM (clean development
mechanism) project of Fengziyan hydropower station cooperating with ENEL in Italy has been
approved by National Development and Reform Commission in November 2006 (Document No. [2006]2397)
and is being registered at the CDM Executive Board (EB) of UN.




4.1 Hydrological Condition



The catchment area above the dam site of Fengziyan
hydropower station covers an area of 3596km2,
 between Wangcang hydrological gauge station and Qingquan hydrological
 gauge station, and it has
the aforesaid hydrological & meteorological features of the basin completely. According to the
data of these 2 hydrological stations, it is analyzed and calculated that the mean annual
precipitation inside the basin is about 1260mm, the mean annual flow 76.17
 m3/s,
the annual mean runoff is ,402 million m3
 and the mean annual runoff depth is 668mm.
The peak flow of design flood with a cycle of 50 years is
 10449m3 /s,
 and the peak flow of check
flood with a cycle of 500 years is 14,509 m3 /s.




4.2 Geological Condition



The geological constitution is relatively simple in this region, and there is no strong
geological movement or any evidence for new constitution activity.


20









 






Therefore, the regional
geological constitution is stable there, and the basic seismic intensity is less than Grade 6.




     Geological condition in the reservoir area: It adopts a reservoir in river channel,
surrounded by solid hills, and the river valley above dam site mostly looks like a “U”
shape. The stratum of reservoir area is constituted by sandstone and clay rock with less
water penetration, and no rupture structure is found for extending out of the reservoir.
Meanwhile, the storage level is relatively low, and there is no permanent leakage issue.
The slope of reservoir bank is gentle, covered with a very thick layer, and underlying rock
is gentle in obliquity, and furthermore, there is no evident poor structure that would lead
to the instability of reservoir bank. Therefore, there would be no large landslip and the
bank slope is rather stable inside reservoir area.



     Geological conditions of dam and plant location: The dam is located in a low hilly area,
and the river valley is long and narrow in unsymmetrical “U” shape. The riverbed is about
100m wide, the slope of left bank is 60° and that of the right bank is 25°~40°. Above both
banks are gentle mesas that have been reclaimed to arable lands. At the dam site, the
riverbed has a gradient of 1‰ mainly with deposits, i.e, its upper is sand & scree with a
thickness of 2.5~3.7m, and followed with complete, thick and dense sandstone. There is no
found rupture formation or dense joint belt. The overlaying at the slope foot of left bank is
0.6~3.1m thick, and the sandstone is exposed at its upside, with the strongly weathered layer
of 2.5~4.5m thick,
and the terrane obliquity is 12°. The right bank is a steep ridge exposed with
sandstone and mud sandstone. The foundation of powerhouse and barrage is cemented thick
sandstone, and the rock keeps relatively complete, its mechanical property is good and load
capability is high. There is no disadvantageous structure surface, and it is stable. The
base rock for two abutments is exposed, and it seems very stable.



4.3 Project Task and Scale



Fengziyan hydropower station is mainly for generation, also functions for navigation because its
navigation channel is classified as Grade 8 and the yearly design navigation capacity is 100,000
tons.




     The installed capacity is 4×3MW, and it is designed to have a mean annual generation
of 46,920MWh and a yearly utilization hour of 3,910h.



     During the planning and preliminary design stage, it is recommended to have a normal
reservoir storage level of 421.00m, but in the construction it is found the actual
investment for resettlement arising from reservoir inundation is much larger than the
budget, thus not only increasing difficulty on construction, but also greatly impacting the
project benefit, therefore the normal storage level is decreased to 420.00m, and also the
shutter gate is heightened to enlarge sluice capability and reduce the flood level inside
the reservoir area. After adjusted, there would basically not involve resettlement, and the
decreased 1m water head



21









 








shall be utilized by the cascade station at its upstream. The
normal reservoir storage level of Fengziyan hydropower station is 420.00m, the dead water
level for power generation is 419.50m and the daily regulating capacity is
 900,000m3.
The normal tail-water level is 406.14m, the minimum tail-water level 405.56m (one unit is
applied for operation), the maximum gross head is 14.44m and the minimum gross head is
13.36m. The design flood level is 428.36m at upstream, and correspondingly the design
flood level at downstream is 418.27m. The check flood level is 431.78m at upstream, and
the check flood level at downstream is 419.10m correspondingly.



4.4 Project Layout and Structure



Fengziyan hydropower station is a project in river
 channel, which is comprised of left bank
non-overflow section, ship lock (scouring sluice), overflow dam section, powerhouse, stepping-up

180.28m long.




4.4.1 Project grade and flood-control standard




     The reservoir storage
 of Fengziyan hydropower station totals 41.2 million m3, so
according to the national “Flood-control Standard (GB50201-94), this project adopts a
medium-sized reservoir and is classified as grade X, and the main structure is also grade 3.
Therefore, a 50-year cycle is adopted for the design flood of barrage, and a 500-year cycle
applied for the check flood. The
flood prevention at the downstream of powerhouse and substation is designed according to a
30-year-cycle standard and correspondingly, the flood level at downstream is 417.17m. The
check flood adopts a 100-year-cycle standard and correspondingly, the flood level at downstream
is 418.72m.



4.4.2 Overflow gate dam




     The overflow gate dam is arranged on the riverbed, among which its leading edge is
120m long, and on the top of fixed weir are erected 12 sets of auto hydraulic shutter gates
with each size of 7m (height)×10m (width). The fixed weir is in concrete structure filled
with gravels. Externally it is a zigzag-line practical weir with the crest elevation of
413.00m and the foundation elevation of 395.50~399.90m. Its height is 17.50~13.1m. In
order to improve the stability, the upstream and downstream of fixed weir both adopt 1.0m
deep cutoff walls, treated with curtain grouting and consolidation grouting. The
dissipation mode adopts underflow type, with a C25 reinforced-concrete stilling basin
erected at downstream, in a size of 55.0m long and 2.5m deep.



4.4.3 Ship lock (scouring sluice)




     A 12m-wide ship lock (scouring sluice) is erected between the powerhouse and the
overflow gate dam, which is composed of three parts such as upstream



22

inside the main powerhouse for the installation and overhaul of turbine-generating unit.
Now the bridge crane has been installed.



     (2) Water-supply & drainage system



     The water supply & drainage system has not been installed, and the following proposal
is suggested at the preliminary design stage:



     Water pump is applied
 for water supply inside
plant, so water is pumped from the dam front and delivered to the related equipment by the
technical water-supply pipe. There are two pumps with the type of 14SA-10C, i.e. one is for
operation, and the other is for standby.



     There is built one

4.5.7 Metal structure




     A trash rack is
 vertically arranged at the front edge of the intake, and fixed on its
hydraulic structure, and the bar is made of 10mm-thick steel piece.



     The trash rack is
 followed with an emergency gate for 4 units. The gate is a
submergible plane sliding steel type, with the hole size of 5.54×3.88m. The gate opens and
closes in static water state, and the headstock gear is composed of 2 sets of monorail
carts and 2 endless-chain manual hoisters.



     At the upstream and
 downstream of ship lock is erected a navigation gate respectively
for passing the boat. At the upstream is a kind of fixed-wheel plane steel gate with its top
exposed, and its size is 6.0m (width)×7.0m (height). At the downstream is a submergible
fixed-wheel plane steel gate, with the size of 6.0m (width)×7.0m (height). The navigation
gates are operated by screw-type headstock gear. In order to meet the function requirements
of working gates, a water-scouring gate valve and a water-release gate valve shall be applied.



     The scouring sluice
 before the upstream working gate is equipped with one working
gate, and the hole size is 6.0m (width)×4.2m (height). The gate is a fixed-wheel plane
steel type and it uses a manual hoister for operating.



     At the outlet of
 draft tube for each unit is equipped the groove for emergency gate,
and one emergency gate is applied for 4 units. The gate is a submergible plane sliding
steel type, with the hole size of 6.435×2.886m. The gate opens and closes in static water
state, and the headstock gear is composed of a duel-hook synchronous electrical hoister and
an automatic girder for lifting and moving the gate.



4.6 Reservoir Inundation and Permanent Land Use



The inundation flood standard of Fengziyan
 hydropower station is as same as that of LiYuan
hydropower station.




     Fengziyan hydropower
 station is originally designed to have a normal storage level of
421.00m, a back Water length of 24.5km on the main reach, and reservoir storage of 15.32
million m3.
 The reservoir mainly inundates residential areas of 116 population from
6615m2 houses, shoals and waste slopes of 32.00 Chinese mu (one hectare equals to 15 Chinese
mu), mottled bamboo of 18.5 Chinese mu, and 2 stone arch bridges



     Based on the
 above-mentioned inundation, a static investment of RMB3,298,900 Yuan is
used to compensate the reservoir inundation, among which RMB2,806,400 Yuan is used for
resettlement in rural area, RMB37,600 Yuan for clearing up the reservoir bottom, RMB227,300
Yuan for other expenses, RMB74,000 Yuan for taxation and RMB153,600 Yuan is ready for
unforeseen expenses.



     According to
 the actual station condition, totally 2.0 Chinese mu of permanent lands
are occupied, and all are wastelands at river shoals. The total



26









 







static investment for
permanent land occupation amounts to RMB51,700 Yuan, in which, RMB24,600 Yuan for
resettlement compensation in rural area, RMB1,900 Yuan as other expenses, RMB23,900 Yuan
for taxation and RMB1,300 Yuan ready for unforeseen use.



     During the construction, it is actually investigated that the 10-year-cycle flood and
its back water inundates 1km-long roads, one bridge and 400 population from over 100
households, so it is estimated that the investment for addressing the inundation issue
amounts to RMB10 million Yuan, thus not only making the construction more difficult, but
also greatly impacting the project benefit. Therefore, it is proposed to decrease the
normal storage level of reservoir to 420.00m, also the height of shutter gate is increased
as to improve the sluicing capacity and reduce the flood level inside the reservoir area.
After adjustment, it basically will not involve resettlement and only a few river shoals
and waste slopes are inundated.

5. Engineering Evaluation for LiYuan Hydropower Station




5.1 Scale of Installed Capacity and Power Generation



The catchment above the dame site of LiYuan Hydropower Station is 4934 km2, only 100 km2 less
from the catchment surveyed by the hydrological station at Qingquan township which is 10 km away
from LiYuan Station. It is reliable to make use of data of. The result would be reliable to make
hydro energy calculation based on that.




     The annual utilization hour of the units for LiYuan Hydropower Station is 3679 h,
which is identical with the current selling price 0.29 Yuan/kWh. Its annual utilization
hour is also close to that of the nearby SHP stations. That means the installed capacity
12000 kW of LiYuan Hydropower Station is reasonable in the short time and the design of
mean annual power output 44.15 million kWh is reliable.



5.2 Main Civil Structures




5.2.1 Pivot layout




     Based on the topographical and geological conditions at the dam site, the position of
the dam axis is rational and the general layout of the pivot structures basically
reasonable.



5.2.2 Spillway gate




     The spillway gate is the hydraulically automatic floating gate mounted on the fixed
weir. The selection of such gate is reasonable. The foundation at the



31









 




spillway gate is sandstone and the geological condition is not homogeneous. But after excavation
and curtain grouting at the dam foundation, it can generally meet the demand of constructing the
dam. The fixed weir is of steel concrete dam, filled inside with sand and gravel. The thickness
of the out covering steel concrete is bigger than 1.5 m. The intensity and stability can meet the
standard demand. The mode of energy dissipation is skipping and surface flowing. The river bed at
down stream is sandstone which has the resistance of flushing. When it is skipping, the amount of
flow is small; When it is surface flow, it is deep at the down stream. So, the scouring force is
weak and dissipation mode is feasible.




     From the site checking, the quality of the fixed weir is satisfactory. There is no
defect, cracks or leakage on the surface. In particular, there is no salient leakage at the
structure foundation. The hydraulically automatic floating gate can block the flood
normally. As told by the station’s operator, the hydraulically automatic floating gate has
experienced flooding for two times, but it still operates normally. The height of the
hydraulically automatic floating gate is 5 m, which is yet to be tested by big floods.



5.2.3 Scouring gate




     The geological condition at the scouring gate is good. Compound structure for the two
orifices of the gate is adopted. At the lower part is the orifice of the gate and at the
upper part is the fixed weir structure for the hydraulically automatic floating gate. The
adoption of this structure is to increase the length of section for the spillway gate, and
to increase the ability to spill the flood. That is both possible and economic. But in
concrete layout, there is no maintenance gate and maintenance platform for the scouring
gate. So, it is not convenient for maintenance.



5.2.4 The power house and the step-up substation




     The foundation of the power house is the complete new rock and curtain grouting
treatment was done, able to meet the engineering requirement. The power house can meet the
stable demand on the whole. It can also meet the intensity demand in structure. The power
house is equipped with the flood protective wall. Both the power house and house
area meet the flood protection requirement.



     By site investigation and checking the drawing, the problems for the power house is as
follows:



     (1) In accordance with the demand of <Design Norms of SHP Stations>, stop gate
should be equipped at the intake so as to prevent the runaway of units due to the fault of
governor, blades blockade or pin breakage in case of emergent shutting off. Now, six gates
share one maintenance gate. It is not safe in case of accident.




32











 





     (2) There is a well for each of the units at the down stream. But the lower part of the
turbine floor is occupied by the well, pump and water pipes on the ground, and there is no
channel at the lower part, so it appears disordered in layout.



     (3) At the upper part of the down stream is equipped with office and rest room for the
generator floor of the power house. The natural lighting and ventilation for the main power
house is poor.



     (4) Through site visit, one unit was operating fully, the surface level at the tail race
was 0.6 m higher than the surface level at the down stream, forming a small drop at the
outlet of the tail race. In fact, the normal tail race of LiYuan Hydropower Station is 4 m
higher than the normal storage level of Luojiatan Station at the down stream. When it is in
normal operation, the back water of Luojiatan Station will not possibly affect the tail water
of LiYuan Station. So, LiYuan Hydropower Station may use the down stream channel as the tail
water level. As the width of down stream is much wider than that at the tail race, the
dropping phenomenon will still exist at the outlet, when the six units are in full operation
for LiYuan Station. Since the rated head of the Station is only 10.5 m, an increase of 0.5 m
head will increase output by % and the annual power generation will also increase by 4%. So,
dredging at the tail race outlet is recommended.



     It is discovered by site visit that many signs of seepage at the upper site wall of
the turbine floor in the power house are spotted. The turbine floor seems wet and dim. The
decoration standard for those above the generator floor is low and it is shabby.



     The position of the step-up substation is reasonable, with layout rational.



5.2.5 Spillway weir at the right bank and boat-lift device




     Construction quality of spillway weir at the right bank and the upper-stream section of
the boat-lifting device is good. No leakage or seepage is found at the down stream. The
down-steam slanting wall of the boat-lifting device hasn’t been under construction, and the
boat-lifting device is not yet mounted.



5.3 Electric Mechanical Equipment and Metal Structures




5.3.1 Turbine




     The turbine type JP502 is selected for LiYuan Station. That type includes the new type
of runner developed by China Hydraulic Research Institute. Its maximum efficiency of the
model is 92.5%, an axial type specially used for low head. After calculation, the selection
is correct. The selection of speed and runner diameter is all proper.



     After calculation and checking, the suction elevation of the units can meet



33









 




the demand, i.e. rational elevation installation. Cavitation or aerifying will not happen.




     Through the visit to the turbine floor, turbines operate stably, normal noise. In the
condition of less reactive power, the active power of the units then exceeded 10%. The
units are considered to be able meet the output demand.



5.3.2 Generator




     Conventional vertical synchronous generators are adopted, operating stably. In the
condition that power factor is 0.8, the rated output 2000 kW could be achieved.



5.3.3 Governor




     It is a proven micro hydraulic governor made in China. Such governor is widely used,
with mature technology, able to meet the demand of unit compatibility. Its governing power
is 50000 Nm., and it is able to meet the demand of unit regulation.



5.3.4 Excitation system




     Excitation system adopts CST , basically able to meet generator regulation demand.



5.3.5 Main electric diagram




     The main electric connection method is reasonable, able to meet the demand of
transmission for the 6 units.



5.3.6 Secondary electric equipment




     Secondary electric equipment can basically meet the demand of electric control and
protection. But the metering function of the computer supervision system is too simple. The
function of temperature and pressure metering at the master unit should be added.. No
record of fault wave is spotted. But it can meet the demand of the power station.



5.4 Environmental Evaluation




5.4.1 Impact to the environment during construction




     There are some residential areas near the engineering site and the impact to the
environment during construction is mainly the wasted production and living water, emission
from the tail gas of the construction machines, aerosols when vehicles pass by, the noise
of drilling, explosions, construction machines operation, vehicles transport and mixing of
the concrete. As the scale is small, the impact is not much, local and temporary. With the
completion of the construction, the impact ends.

5.4.2 Prediction and evaluation of ecological environment




     The shape of the LiYuan reservoir is narrow and the station is of river-bed-type. The
surrounding hills are quite gentle and there is no sliding potential. After the construction
of the dam, certain bush and weed will be flooded. In the initial stage of the reservoir
operation, the organic component will be increased than the natural river channel. But the
station is of run-off type, with quick exchange of water and self-purification ability high,
eutrophia will not occur. The impact to the water quality is minimal.



     The engineering construction and inundation refers to only the rural vegetation, bush
and wasteland, no impact to the precious vegetables. During the construction, there will
be some impact to some wild animals in the construction area and areas nearby in terms of
noise and interference of construction personnel. But after the construction, such
interference will soon end. After the formation of the reservoir, the water will become
clean, beneficial to the growth of various animals down stream of the dam. With the dam,
some impact will have on the swimming back of some fish and breed. However, such impact is
already there with the dam upper stream.



     The construction area is vast and flat, with no impact on the erosion of water soil at
the construction area.



5.4.3 Prediction and evaluation on the social environmental impact




     The construction of LiYuan hydropower station with installed capacity 12000 kW, mean annual power
generation 44.15 million kWh and annual sale income 11.56 million Yuan, will become the main power
source after construction. It will play a big role in promoting the social and economic progress.



     About half of the investment will be used for buying construction material and payment
of labor force, beneficial to pull forward the local economy and increasing the opportunity
of local employment.



     The construction of LiYuan will change the industry structure, improve the energy
structure, transform to the renewable energy of Cangxi county in certain way, a new chance
for the sustainable development of local economy.



6. Engineering Evaluation for Fengziyan Hydropower Station




6.1 Scale of Installed Capacity and Power Generation




The catchment above the dam site of Fengziyan Hydropower Station is



35









 




3596km2, between Wangcang Hydrology Station and Qingquan township Hydrology. The
hydrological data adopted is sufficient, reliable and accurate. The analysis and calculation on
the run-off at the dam site is reasonable.. It is reliable to obtain the result of hydro energy
calculation based on such data.




     The installed capacity of Fengziyan Hydropower Station is 12000 kW, mean annual power
generation 46.92 million kWh and annual utilization hour 3910 h. The installed capacity is
reasonable and the mean annual power generation 46.92 million kWh designed is reliable.



6.2 Main Structures



As the engineering is under construction, it is not possible to evaluate the quality of the
structures to be constructed and operation condition after storing water.




6.2.1 General pivot layout




     Based on the topographical and geological conditions at the dam site of Fengziyan
Hydropower Station, the position of the dam axis is rational and the general layout of the
pivot structures reasonable.



6.2.2 Geological condition of the engineering




     The geological and reconnaissance survey at the preliminary stage can meet the design
demand. From the geological reconnaissance and site excavation, the foundation rock of the
dam and power house is stable and sound. There is no disadvantageous structure facet and
general engineering and geological conditions are good, able to meet the engineering demand
after some treatment.



6.2.3 Spillway gate




     The spillway gate is the hydraulically automatic floating gate mounted on the fixed
weir. The selection of such gate is reasonable. The foundation at the spillway gate is
brownmillerite and argillaceous sandstone. Generally speaking, the geological condition is
good. After excavation and curtain and consolidation grouting at the dam foundation, it can
generally meet the demand of constructing the dam. The fixed weir is of embedded rock
concrete structure. The structure size designed to meet the need of the hydraulic automatic
floating gate and flood discharging can completely meet the demand of standard to intensity
and stability. The energy dissipation mode is bottom flow one, equipped with concrete
dissipation pond which is also reliable.



     One section of the fixed weir for the spillway has been finished. After site checking,
its engineering quality is good. o



36









 





     To reduce the inundation loss at the upper reach in case of flooding, the height of
the hydraulic automation floating gate to be mounted on the fixed weir of the spillway is 7
m, which has certain risk. As one of the sections for the fixed weir has been constructed
for one month and the floating gate has been ordered, the further appraisal of the gate is
meaningless. But be prepared for the potential risks.



6.2.4 Ship lock(sluice gate)




     It is feasible to combine the ship lock and the sluice gate together, and the
intensity and stability are reliable. The construction quality of the sluice gate is
good.          . o



6.2.5 Power house and step-up substation




     The foundation of the power house is complete new rock, and treatment of consolidation
and curtain grouting have been made, able to meet the engineering demand. The layout of power
house is reasonable. Both the power house and house area can meet the demand of flood
protection. o



     The following problems exist in the power house:



     (1) Four units share one maintenance gate and there is no stop gate, affecting the
safety of the units.



     (2) There is no orifice for man at the tail draft, inconvenient for the maintenance of
the turbines.



     (3) The side wall of the main power house at the down reach is too high.



     The natural lighting and ventilation is poor.



     The position of the step-up substation is proper, and the construction quality of the
power house is good.



6.3 Electric Mechanical Equipment and Metal Structures



As Fengziyan Hydropower Station is not yet commissioned and most equipment is not yet installed,
so no evaluation is made on the operation condition of the equipment.




6.3.1 Turbine




     It is reasonable to select 4 turbines for Fengziyan Hydropower Station. The types
selected are similar to those of LiYuan Station, with high efficiency. After calculation,
the selection is correct, the parameters selected reasonable, able to meet the power
generation demand.



6.3.2 Generator




37









 





     The generators selected match the turbines quite well and the structure mode also meets
the demand of the Station and the turbines. The type selected is correct, with rational
parameters. o



6.3.3 Governor




     The operation functions of the governor could meet the demand of
unit regulation.



6.3.4 Excitation system




     The excitation system selected could meet the demand of excitation for the Station.



6.3.5 Main electric connection




     Main connection mode is reasonable.



6.3.6 Layout of the electric mechanical equipment




     The layout of the electric mechanical equipment in the power house is rational.



6.4 The Environmental Evaluation



There are no residential areas near the engineering site and the impact to the environment during
construction is mainly the wasted production and living water, emission from the tail gas of the
construction machines, aerosols when vehicles pass by, the noise of drilling, explosions,
construction machines operation, vehicles transport and mixing of the concrete. As the scale is
small, the impact is not much, local and temporary. Through the protective measures of the
construction organizations, the impact could possibly be reduced. With the completion of the
construction, the impact ends.




     The natural and social environment of Fengziyan hydropower station and that of LiYuan
Station is quite similar. The development mode and objectives are also similar. Thus, the
prediction to the ecological, environmental and social impact is about the same.



7. Development prospect




7.1 Local Social and Economic Developing Status




The total area of Sichuan is 485000 km2, with the population 87.004 million by the end
of 2004. Most area lies in the humid monsoon region, with rich



38









 




precipitation, except for the area which is high in elevation in the west.




     Many kinds of energies in Sichuan are available, with the features of little amount of
coal and oil, rich gas and rainfall. Rich hydropower potential is the biggest resource in
the province. The proportions of its resources are:
hydropower potential 75.98%, coal resource 23.27%, natural gas 0.75. The theoretical
hydropower potential is 142.7 million kW, technically exploitable 103.5 million kW,
representing 21.11 and 27.33% respectively in China, with annual power generation 401.7
billion kWh. Most of the hydropower potential is concentrated in the 3 big rivers:
Jinshaojiang, Yalongjiang and Daduhe. The technically exploitable amount reaches 81.53
million kW, representing 78.8% in the whole province. By 2004, the rate of exploited amount
in the province was 11.1%, lower than the national average figure 18.5%. So, the potential
of development is huge. There is small amount of coal resource, mainly distributed in
Panzihua and some southern areas in the province. The total coal reserve is 7.09 billion t,
representing less than 1% of the country’s total. But it is rich in natural gas and its
reserve accounts for 7180 billion m3 , among which 633.6 billion m3
has been proved in 2002. In 2004, the amount of natural gas produced reached 9.449 billion
m3. Apart from the supply to the civil use, it is used mainly for chemical
industry material. After 30 years of use, the oil resource is getting exhausted. Currently,
over 90% of the oil consumption is from outside of the province.



     Sichuan province lies in the subtropical region, with advantageous natural conditions,
rich in agricultural products. It has long been an important base of such products as
grain, pork, rape vegetable, citrus (orange) and tung oil, enjoying a reputation as “land
of abundance”.



7.2 Power Development Status and Planning in Sichuan Province




7.2.1 Power development status in Sichuan province




     The electric power source in Sichuan province is mainly hydropower. By the end of
2005, the total installed capacity was 22.9588 million kW, of which 8.0103 million from the
thermal power, representing 34.8%, 14.6485 million kW from the hydropower, representing
65.11%. The total power generation was 101.7 billion kWh, increased by 14.86% as compared
with that in previous year.



     Together with the rapid power source development, the grid development was also
strengthened. The main110kV, 220 kV, 500 kV diagram system has primarily been formed in
Sichuan power grid. According to the supply regions, 5 regions of power supply can be
classified, namely, west Sichuan (including Chengdu, GuangYuan, Mianyang, Deyang, Leshan and
Ya-an), south Sichaun (Neijiang, Suining, Zigong, Yibing and Luzhou), east Sichuan
(Nanchong, Bazhong, Daxian, Guang-an), Panxi of Sichuan (including Panzihua, Liangshan) and
northwest Sichuan (Aba and Ganzi prefectures). The 24 transmission lines



39









 




of 500 kV, 2985km, as in the Sichuan grid was successfully built and put into operation. 220 kV
transmission line for 8119 km, 110 kV transmission line for 10537 km. There have been built 8
substations of 500 kV with capacity 6 million kVA, 70 substations of 220 kV with capacity 13.98
million kVA, 110 kV substation of capacity 17.34 million kVA.




7.2.2 Electric power development planning in Sichuan province




     In accordance with the <Investigation & research report on grid planning of Sichuan
and Chongqing by 2020> and < Investigation & research report on electricity
transmission from west to east in mid Sichuan province> completed in Dec 2003, the
prediction of load development in Sichuan province from 2005 to 2020 is as follows: the
maximum power generation load in 2005 is 11.13 million kW, electricity demand 94.4 billion
kWh in the whole province; by 2010 the maximum power generation load 21.81 million kW and
maximum power demand 124.1 billion kWh; by 2015 the maximum power generation load 29.32
million kW and maximum power demand 166 billion kWh; by 2020 the maximum power generation
load 36.89 million kW and maximum power demand 208.5 billion kWh,



7.2.3 Planning of supply to outside of the province




     Sichuan is rich in energy resources, especially the hydropower resource. The technical
exploitable hydropower potential is 120 GW, representing 27.2%, rated as the first in the
country. By the end of 2005, the hydropower resource exploited reached 12%, a big potential
to tap. As the exploitation rate of hydropower is still low and the resource advantage has
not yet turned into economy advantage, it is an important step in the whole implementation
strategy of the west area development campaign to make use of electricity transmission from
west to east and develop the rich clean hydropower potential in the province so as to realize
its electricity transmitted out.



     According to some documents issued by the province, the planning for the transmission
of electricity from west to east is: By 2010, the installed capacity of transmission out 8
million kW and the amount of energy 38 billion kWh; By 2015, the installed capacity of
transmission out 12 million kW and the amount of energy 57 billion kWh; By 2020, the
installed capacity of transmission out 16 million kW and the amount of energy 76 billion
kWh



7.3 The Local Power Development Status and Planning



Cangxi county power grid belongs to the west power grid supply area of Sichuan province.
Currently there is one substation of 110 KV, with capacity 71500 kVA, connecting GuangYuan city
and Sichuan power grid. There are 8 substations of 35 kV with capacity 33800 kVA, 150 km line of
35 kV.




     In 2004, the maximum load of Cangxi county was 20200 kW, annual



40









 




power consumption 93.2 million kWh. But the installed capacity in the county was only 10700 kW,
annual power generation only less than 30 million kWh. Over 2 thirds of its electricity was
supplied by Sichuan grid.




     With the economic development of Cangxi county in the recent years and after reform of
the rural power grid, the growth of electricity consumption exceeded that of the economic
growth. According to the electrification planning of Cangxi county, the maximum load will
reach 42000 kW with annual electric power 184 million kWh by 2008. By 2010, the maximum
load will reach 50000 kW with annual electric power 210 million kWh. By 2015, the maximum
load will reach 70000 kW with annual electric power 280 million kWh.



     In accordance with the development outline for GuangYuan city, it points out that
“Build a group of medium and small hydropower stations so as to promote the cascade
hydropower development for Jialingjiang, Bailongjiang and Donghe basin and SHP
exploitation”. To solve the problem of weak grid structure, a substation of 220 kV will
built in Cangxi, further improving the rural grids.



7.4 Development of Donghe Cascade Hydropower Stations and Market Demand



The last cascade SHP station — LiYuan Hydropower Station in the Donghe cascade has been built now
and its second cascade station —Fengziyan Hydropower Station is being built, to be put into
commissioning in Sept 2007. According to the present schedule, the remaining 4 cascade stations
will be commissioning in 2009 and 2010. The installed capacity of LiYuan Hydropower Station is
12000 kW, mean annual power generation 44.15 million kWh. The installed capacity of Fengziyan
Hydropower Station is 12000 kW, mean annual power generation 46.92 million kWh. After
commissioning of the two stations, the total installed capacity in Cangxi grid in 2008 will be
only 35000 kW with annual power generation 120 million kWh. According to the load forecast of
Cangxi county, it could be adsorbed wholly by Cangxi power grid.




     The remaining 4 stations of Donghe cascade stations are put into commissioning, the
installed capacity in Cangxi grid will reach 73000 kW with annual power generation 260
million kWh. Meanwhile, the maximum load in Cangxi grid in 2010 will be 50000 kW, with
annual power demand 210 million kWh.. By that time, there will be some surplus energy to be
sent to Sichuan grid, but mainly concentrated in the rainy season. The construction of
substation of 220 kV will facilitate the transmission out. Though Sichuan is rich in
hydropower resource, its hydropower potential is mainly located in the rivers of the west
part. The areas able to send out the energy could only possibly be from the western part of
the province. The energy which is sent out from Cangxi county is not enough and it is
quickly
adsorbed by the adjacent counties. By 2015, the power and energy in Cangxi county will
appear surplus in rainy



41









 




season, but not enough in dry period, in need of supplement by the large grid. After 2015, the
power and energy in Cangxi county will have shortage, to be supplied by large grids.




     In short, the product of Donghe cascade hydropower stations will have big market
potential to adsorb in either short term or long term.



7.5 Forecasting on the Adjustment of Selling Price to the Grid



Currently, the selling price of other SHP station in Cangxi county is 0.27 Yuan kWh, 0.288 Yuan
kWh in GuangYuan city and 0.29 Yuan kWh in Donghe cascade SHP stations. The price in Donghe is
actually higher than other places in Cangxi county, and higher even in GuangYuan city. It could
be predicted that the increasing space is not much in the near future.




7.6 Upper Cascade Development Prediction in the Long Term



In accordance with <General planning report of hydropower development in Sichuan province>,
at the upper reach of Donghe River in Wangcang county, the Guanziba reservoir has been planned.
Its construction will have influence on the cascade stations planned. So, analysis will be made
dynamic technology indexes of the cascade stations in the long term.




     Guanziba reservoir lies at upper reach of the basin and dam site is 7 km off the
Wangcang county center, with catchment area 2633km2, mean annual precipitation
2.09 billion m3. The main function of Guanziba reservoir (grade II) is for
irrigation in combination with generation and flood prevention. The normal 3 storage level
is 573 m, max dam height 116 m, total storage 565 million m , valid storage 385 million m
m3. The installed capacity is 25000 kW, mean annual generation 116 million kWh.
The intake lies at the left bank of the dam, intake elevation 531 m, designed diversion
flow 80 m3 /s.



     The irrigation area covers the cultivate land between the left bank of Liujianghe and
right bank of Bahe river including Wangcang, Nanjiang, Bazhong, Pingchang, Daxian, Juxian
Yilong and etc. The planned irrigation area is 2.124 million mu, the gross water supply
from the reservoir 729 million m3.



     Impact analysis of Guanziba reservoir impact after construction to the planned cascade
development, in accordance with <Planning report of hydropower resource of Cangxi section
at Donghe River> :



     According to the hydropower engineering of similar nature, it is estimated that Guanziba
reservoir could be built in 10 years at least. In another 15 years, the main engineering and
equivalent facilities will be completed and put into operation. So, impact of the reservoir
will be on the various cascade stations.



     At the initial stage that the reservoir is just completed, the necessary



42









 




facility is not fully available, so the irrigation water in the reservoir is less and it has a
bigger role to play in regulation for the cascade stations below (especially in dry season).




     After completion of Guanziba reservoir, the water for the cascade stations below will
be less by 729 million m3 annually, representing 24-34% for each cascade
station. But before the completion of the reservoir, the amount of water abandoned each
year amount to over 41% and the reservoir can hold flooding water around 700 million
m3. After the completion of the reservoir, the available water amount for the
cascade stations below seems slightly less, each of the cascade stations has already paid
back the loan after 25 years and gained benefit. Hence, the construction of Guanziba
reservoir has little impact to the cascade SHP stations below in fact.



8. Economic Evaluation




8.1 General



The main task of the LiYuan Hydropower Station and Fengziyan Hydropower Station is power
generation, in combination with navigation. The installed capacity of LiYuan Hydropower Station
is 6x2000 kW, the designed mean annual power generation 44.15 millionkWh, started its
construction on 18 Nov in 2004 and put into commission in August 2006. The installed capacity of
Fengziyan Hydropower Station is 4x3000 kW, the designed mean annual power generation 46.92
million kWh, started its construction in Dec 2005 and it is now under construction. I will be put
into commission in Sept 2007.




     The economic evaluation for LiYuan Hydropower Station and Fengziyan Hydropower Station
has been based on the current tariff policies and regulations concerned.



8.2 Investment Plan



In the first year, 154 million Yuan will be primarily invested to purchase LiYuan and Fengziyan
Hydropower Stations for the project.. For the convenience of calculation, the construction period
of FengziYuan Station is set as one year.




     All the fund for the project is self mobilized.



     The proportion of current capital for the Station is quite small and after the
purchase, there will soon be sale revenue for the LiYuan Station. So, the annual current
capital is not counted here.



8.3 Basic Figures




     (1) Amount of energy selling to the grid




43












 





     The amount of annual power generation for the Station is 44.15 million kWh in the
first year and 91.07 million kWh starting from the second year.



     In accordance with the actual situation of LiYuan and FengziYuan Hydropower Stations
in the recent years, the valid energy parameter is 0.95, station service power is 0.5% and
the transformation and transmission loss is 4.5%.



     (2) Revenue from power generation



     The financial evaluation is made according to independent account as a power
generation item within the grid. Based on the verification by price bureau of Canxi county,
Sichuang province, the interim selling price 0.29 Yuan/kWh to the grid is adopted. The
amount of energy from LiYuan is 39.85 million kWh with annual income 11.5579 million Yuan.
The amount of energy from Fengziyan Hydropower Station is 42.36 million kWh with annual
income 12.283 million Yuan.



     (3) Tax and additional tax



     X VAT



     According to the related regulations, 6% as VAT from SHP generation income is levied.



     X Sale tax



     It includes city maintenance construction, education tax and local education tax,
levied according to the base of VAT. They are 5%, 3% and 1% respectively.



     (4) The sale cost of the power generation



     It includes maintenance fee, staff wage and welfare, water resource fee, material fee,
and other expenses etc.



     1% of the total fixed asset is set as the maintenance fee. It is 770000 Yuan for LiYuan
Hydropower Station and 770000 Yuan for Fengziyan Hydropower Station.



     Wage and welfare: There are 20 staffs for LiYuan Hydropower Station and the mean
annual wage 12000 Yuan per person. Thus, the total amount of wage is 240000 Yuan. 14% of
the total wage is set as the welfare for the staff and so the total welfare amount is 33600
Yuan for LiYuan Station. After commissioning, Fengziyan Hydropower Station will have 40
staffs, the mean annual wage 12000 Yuan per person. Thus, the total amount of wage is
480000 Yuan. 14% of the total wage is set as the welfare for the staff and so the total
welfare amount is 67200 Yuan.



     The rate of water resource fee is calculated as 0.0025 Yuan/kWh, thus the fee is 99600
Yuan for LiYuan Station, 105900 Yuan for Fengziyan Hydropower Station.



     The rate of material is calculated as 5 Yuan/kW, then it is 60000 Yuan
for LiYuan Station, 60000 Yuan for Fengziyan Hydropower Station.



44









 





     Other fees are calculated as 18 Yuan/kW, it is 144000 Yuan for LiYuan Station,
144000 Yuan for Fengziyan Hydropower Station.



     The sale cost of the power generation is 2.7007 million Yuan.



     (5) Income tax



     The income tax in the first and second year calculating from the day of power
generation will be exempted. In the third, fourth and fifth year, 17% will be levied and
33% will be levied five year later.



8.4 Evaluation Methods




The payoff period of the static investment should be calculated. o



     The return period of the static investment refers to the ratio of total investment of
the project to the power generation income deducting the power generation sale cost, tax and
addition (namely VAT, Xsale tax addition). Thought the calculation, the payoff period of the
static investment is 7.86 years.



8.5 Evaluation Conclusions




The total installed capacity of LiYuan hydropower station is 6×2000kW with the design mean annual
power generation 44.15 million kW; the total installed capacity of Fengziyan hydropower station
is 4×3000kW with the design mean annual power generation 46.92 million kW. The investment cost of
both two stations is 6417 Yuan per kW.



     Thought the calculation, the payoff period of the static investment is 7.86 years. o



9. Appraisal Conclusions




     (1) Donghe cascade stations lie in Cangxi county and they are of river-bed type
station with low head and large flow. LiYuan Hydropower Station is the last sixth cascade
station planned in Cangxi section of Donghe and it started its construction on 18 Nov 2004
and put into commissioning in Aug Fengziyan Hydropower Station is the 2nd of the six
cascades stations in the Cangxi section and it started its construction in Dec 2005 and now
it is still under construction, but it is planned to put into operation in Sept 2007. The
installed capacity of LiYuan Hydropower Station is 12000 kW with designed mean annual power
output 44.15 million kWh. The installed
capacity of Fengziyan Hydropower Station is 12000 kW with designed mean annual power
output 46.92 million kWh. After verification and appraisal, the installed capacity of the
two stations is reasonable and the designed mean annual power output guaranteed.



45









 





     (2) After checking the related drawings and site investigations, the site selection of
LiYuan Hydropower Station is correct. The general pivot layout is basically reasonable. The
geological condition around the power house and the dam site is sound. After some
treatment, it can meet the requirement of the engineering. The design of all the key civil
works can meet the requirement of intensity and stability. Some defects of construction
quality around the power house are spotted with the leakage in some part. The construction
quality of other civil structures seems OK, no defects, cracks or leakage detected. The
pivot civil structure can basically meet the requirement of operation.



     The selection of main electric and mechanical equipment of LiYuan Hydropower Station is
rational. Its main and auxiliary equipment can basically meet the requirement of Station’s
operation. The equipment can meet the requirement of operation in terms of function. The
layout of water, gas and oil is able to meet the requirement of use basically. A stop gate
at the intake is lacking, unsafe. Generally speaking, the electric and mechanical equipment
can basically meet the operation requirement, which could be improved gradually in future.



     (3) The site selection of Fengziyan Hydropower Station is correct. The general pivot
layout is reasonable. The geological condition around the power house and the dam site is
sound. After some treatment, it can meet the requirement of the engineering. The design of
all the key civil works can meet the requirement of intensity and stability. From observing
the civil structures already built, the construction quality is satisfactory. From the
design data and site conditions, the pivot civil structures could meet the operation
requirement.



     The selection of main electric and mechanical equipment of Fengziyan Hydropower
Station is rational. Its main and auxiliary equipment which has been ordered can basically
meet the requirement of Station’s operation. The equipment can basically meet the
requirement of operation in terms of function. A stop gate at the intake is lacking,
unsafe. Generally speaking, the design of main electric and mechanical equipment is
rational in terms of function, able to meet the operation requirement.



     (4) The payoff period of the static investment of the LiYuan and Fengziyan Hydropower
Stations is 7.86 years and the project is feasible. After the implementation of CDM with
Italian Power Corp, the benefit of the two stations will be increased. With the upcoming
adoption of new tax system, the benefit of the project will be increased as well.



     (5) According to the development plan, the products of Donghe cascade stations will
find good market in the near future or in the long run. The cascade development at the
upper reach does not have much impact to this project. The current selling price is proper
and it will be increased with the regulation of policy.



     (6) In regard with the remaining four cascade stations in Cangxi section of Donghe,
the exploitation condition is also good, with suitable scale and attractive economic
indexes. The CDM application in collaboration with Italian



46









 




Power Corp has been replied and approved by China’s State Development & Reform Commission. The
preliminary design and all the necessary documents for approval have been ready for the remaining
four stations, waiting for the start of construction after settling the fund. After the
implementation of purchasing LiYuan and Fengziyan Hydropower Stations, it is time to engage in
the development of other four stations, potential reduce the investment cost and increasing the
scale benefit of the investment.




     In summary, the resource conditions of LiYuan and Fengziyan Hydropower Stations are
good. Both design and construction of the pivot structures can meet the requirement of the
intensity and stability, as well as the operation and utilization, and the potential bright
prospect for the remaining four sites of further exploitation. So, the project is rated as
feasible.

station has obtained the approval.




Introduction to the Construction Environment of the Power Station




(1) Introduction to Donghe River Basin



Donghe River is one of the first-level branches of Jialing River, and is located in the left bank
or medium- and up-stream of the latter. Donghe River is originated from the south of Micangshan
Mountain, one of the Qinling Mountains. Its total length is 293km, and its total drainage area is
5040km2. According to the hydrometeorological data in the past years, its average flow is
109.1m3/s. Donghe River passes through Cangxi County

in its medium- and down-stream. In the territory of Cangxi County, Donghe River’s route is 110.4km
long, and its drainage area is 1285.00km2.



Cangxi County is located in the medium-stream of Jialing River, upstream of the Yangtze River,
south of Daba Mountains and the northern margin of Sichuan Basin. The whole county area is 2331km2.
By virtue of its wonderful monsoon
humid subtropical climate, Cangxi County has 380 million m2 of cultivated land on which 767,000
residents live. Under its territory, there are totally 39 townships. On its east lie Bazhong and
Nanjiang, on its south lies Langzhong, on its west lies Jiange, and on its north lies Wangcang and
Yuanba. Cangxi County features numerous foothills and intervals that are about 380-1000m high.
Jialing River and Donghe River flow through its hinterland. Within their drainage areas, therea are
about 50,000m2 of cultivated land, 450 million m2 of forest land and 20,000m2 of barren lands.



The economy of Cangxi County is dominated by agriculture. Since being located in mountainous areas,
Cangxi County features poor soil, lack of arable land, and large population, so its economic base
is relatively lagged. Since the beginning of reform and opening up, the economy of Cangxi County
rapidly develop, people’s living standards have been markedly improved, the speed of economy
development has maintained a growth rate of more than 10% for 13 years consecutively. Its
industrial structure is becoming more rational. In the county, the natural resources are very rich.
Its natural gas reserves is 5 billion m3, its water resources capacity can be developed up to 1.018
million kW. Currently, natural gas is exploited by the government, and begins to benefit local
industry and local residents, and water resources including Liyuan Power Station that is just put
into operation, only account for 2.2% of the exploitation capacity, the exploitation potential of
hydropower resources is very huge.




2. Hydrometeorology



Donghe River valley belongs to region of humid subtropical monsoon climate, located in the basin
margin, alternatively affected by rainstorm zone of Daba mountain and small rainstorm zone of
Longmen, is strong rainstorm climate system, more low troughs and low vortexes, with a feature of
mild climate and more rainfall. Donghe River Basin affected by the rainstorm, the average rainfall
was 1000mm for many years, annual

rainfall has not been much change, and distribution in the year is extremely uneven. In the river
basin, summer and autumn the rainstorm is frequent and intense, last a short time, and floods
violent rise and drop suddenly and sharply. Area from Jiulongshan to Qiping along the upper reaches
of the Donghe River is in the eastern rain area, the average rainfall is 140mm per 24 hours,
Cangxi, Wangcang is 120mm, to the south gradually reduce to 100mm, the heavy rain occurs in 6-9
months, account for more than 50% of the whole year, the process lasted about a rainstorm is 3-7
days. Donghe River below from Wangcang belongs to warm dry winter climate, the average temperature
in January is above 5°C, the average temperature in July is above 25°C, the temperature changes
little in the year, vertical difference and difference between the South and North are significant.



In upstream of Donghe River there is Wangcang Hydrometric Station
(control area is 2701km2),
downstream there is Qingquanxiang Hydrometric Station (control area is 5011km2). These two
hydrometric stations have a longer hydrologic data, can as a reference station used for hydrology
analysis and calculation of rundle Power Stations in the basin. The flow of Donghe River is
supplemented mainly by rainfall, plentiful water, but larger changes in a year and different years.
According to the measured data of Qingquanxiang Hydrometric Station, the largest measured annual
average flow is 246 m3/s (1981), minimum annual average flow is 37.2 m3/s (1979). The ratio of
maximum annual average flow and minimum annual average flow is 6.61. The main runoff in the year is
concentrated in May to September, the runoff volume accounts for the total runoff volume 79.7%, the
runoff of June, July, August is the most plentiful; dry season is from October to next April,
mainly supplemented by groundwater, accounts for 20.3% of the total annual runoff, of which,
January and February are the most dry months, accounts for 2.5% of the total annual runoff.



Flood of Donghe River is formed from rainstorm, rainstorms and floods occur in
the same time. Flood season is from June to September, and is mostly concentrated from the July to
August. The duration of a flood generally is 3-5 days. Internally changes of the largest peak flow
are large, measured ratio of maximum and minimum reached
26.4%

The total length of Donghe River is 293km, natural gap is 1536m, the riverway average drop 5.2‰,
river basin area over estuary is 5040km2, and over the past years, the average flow over estuary is
109.1m3/s, theory hydropower reserves is 237,000kW, it is a medium-sized river with rich water
resources in Sichuan Province. Limited by the natural conditions and socio-economic conditions, the
degree of development and utilization of hydropower in the Donghe River valley is low, the Donghe
River Station has been built in the territory of Wangcang County at the upper reaches of the
mainstream of the Donghe River, installed capacity is 3,000 kW, the Luojiatan Station has been
built in the territory of Langzhong County at downstream, installed capacity is 5,000 kW.



In the Territory of Cangxi County, the length of the Donghe River is 110.4km, the centralized gap
is 78m, and riverway average slop is 0.71‰. As early as 1987, Cangxi County Hydropower Bureau
prepared the “Planning Report of Donghe River Hydropower in Cangxi County (Cangxi Reach)”, made
development program for four levels stations at mainstream of Donghe River in the Territory of
Cangxi County. The program is to built higher dam, at this stage it is difficult to implement,
mainly because to inundate too much farmland and immigrants, and bring social problems and
ecological environment problems which are difficult to solve.



Therefore, Cangxi County Hydropower Bureau entrusted Nanchong Hydropower Electric Power
Construction Exploration Design and Research Institution of Sichuan Province in 2005 to re-plan the
development of hydropower resource at this reach. According to the results of planning of “the
Planning Report for Hydropower Resources of the Donghe River of Cangxi” prepared by this
institution in December 2005, the planed reach, river slop is small, many farmlands and counties
are distributed on the banks of river, dense population, is not suitable to the construction of
large reservoirs, also there is not terrain conditions to build water-transferred water power
station, it is suitable to adopt multi-level low-dam development program. Through comparison to
many programs, confirmed to adopt six levels development programs including Dongxi

acquisition and operation of 100,000kW-and-above Power Stations in China. Its shares are on the
stock exchange in the London Stock Exchange Alternative Investment Market (ATM).




II. Introduction to the Power Station




(1) Introduction to Donghe River Basin



Donghe River is one of the first-level branches of Jialing River, and is located in the left bank
or medium- and up-stream of the latter. Donghe River is originated from the south of Micangshan
Mountain, one of the Qinling Mountains. Its total length is 293km, and its total drainage area is
5040km2. According to the hydrometeorological data in the past years, its average flow is
109.1m3/s. Donghe River passes through Cangxi County in its medium- and down-stream. In the
territory of Cangxi County, Donghe River’s route is 110.4km long, and its drainage area is
1285.00km2.



Cangxi County is located in the medium-stream of Jialing River, upstream of the Yangtze River,
south of Daba Mountains and the northern margin of Sichuan Basin. The whole county area is 2331km2.
By virtue of its wonderful monsoon humid subtropical climate, Cangxi County has 380 million m2 of
cultivated land on which 767,000 residents live. Under its territory, there are totally 39
townships. On its east lie Bazhong and Nanjiang, on its south lies Langzhong, on its west lies
Jiange, and on its north lies Wangcang and Yuanba. Cangxi County features numerous foothills and
intervals that are about 380-1000m high. Jialing River and Donghe River flow through its
hinterland. Within their drainage areas, therea are about 50,000m2 of cultivated land, 450 million
m2 of forest land and 20,000m2 of barren lands.



The economy of Cangxi County is dominated by agriculture. Since being located in mountainous areas,
Cangxi County features poor soil, lack of arable land, and large population, so its economic base
is relatively lagged. Since the beginning of reform and opening up, the economy of Cangxi County
rapidly develop, people’s living standards have been markedly improved, the speed of economy
development has maintained a growth rate of more than 10% for 13 years consecutively. Its
industrial structure is becoming more rational. In the county, the natural resources are very rich.
Its natural gas reserves is 5 billion m3, its water resources capacity can be developed up to 1.018

margin, alternatively affected by rainstorm zone of Daba mountain and small rainstorm zone of
Longmen, is strong rainstorm climate system, more low troughs and low vortexes, with a feature of
mild climate and more rainfall. Donghe River Basin affected by the rainstorm, the average rainfall
was 1000mm for many years, annual rainfall has not been much change, and distribution in the year
is extremely uneven. In the river basin, summer and autumn the rainstorm is frequent and intense,
last a short time, and floods violent rise and drop suddenly and sharply. Area from Jiulongshan to
Qiping along the upper reaches of the Donghe River is in the eastern rain area, the average
rainfall is 140mm per 24 hours, Cangxi, Wangcang is 120mm, to the south gradually reduce to 100mm,
the heavy rain occurs in 6-9 months, account for more than 50% of the whole year, the process
lasted about a rainstorm is 3-7 days. Donghe River below from Wangcang belongs to warm dry winter
climate, the average temperature in January is above 5°C, the average temperature in July is above
25°C, the temperature changes little in the year, vertical difference and difference between the
South and North are significant.



In upstream of Donghe River there is Wangcang Hydrometric Station (control area is 2701km2),
downstream there is Qingquanxiang Hydrometric Station (control area is 5011km2). These two
hydrometric stations have a longer hydrologic data, can as a reference station used for hydrology
analysis and calculation of rundle Power Stations in the basin. The flow of Donghe River is
supplemented mainly by rainfall, plentiful water, but larger changes in a year and different years.
According to the measured data of Qingquanxiang Hydrometric Station, the largest measured annual
average flow is 246 m3/s (1981), minimum annual average flow is 37.2 m3/s (1979). The ratio of
maximum annual average flow and minimum annual average flow is 6.61. The main runoff in the year is
concentrated in May to September, the runoff volume accounts for the total runoff volume 79.7%, the
runoff of June, July, August is the most plentiful; dry

109.1m3/s, theory hydropower reserves is 237,000kW, it is a medium-sized river with rich water
resources in Sichuan Province. Limited by the natural conditions and socio-economic conditions, the
degree of development and utilization of hydropower in the Donghe River valley is low, the Donghe
River Station has been built in the territory of Wangcang County at the upper reaches of the
mainstream of the Donghe River, installed capacity is 3,000 kW, the Luojiatan Station has been
built in the territory of Langzhong County at downstream, installed capacity is 5,000 kW.



In the Territory of Cangxi County, the length of the Donghe River is 110.4km, the centralized gap
is 78m, and riverway average slop is 0.71 ‰. As early as 1987, Cangxi County Hydropower Bureau
prepared the “Planning Report of Donghe River Hydropower in Cangxi County (Cangxi Reach)”, made
development program for four levels stations at mainstream of Donghe River in the Territory of
Cangxi County. The program is to built higher dam, at this stage it is difficult to implement,
mainly because to inundate too much farmland and immigrants, and bring social problems and
ecological environment problems which are difficult to solve.



Therefore, Cangxi County Hydropower Bureau entrusted Nanchong Hydropower
